Is it safe to donate blood and its components?

Regular donors annually undergo a medical examination, including tests, fluorographic examination of the chest organs, electrocardiography, etc.

Only sterile disposable instruments are used for blood collection. Reuse of tools is excluded. For plasmapheresis and plateletpheresis, the so-called. closed systems in which blood is drawn automatically using special equipment, with minimal intervention from medical personnel.

Compliance by donors with the recommendations of the Blood Center staff can improve the tolerance of donation.

The effect of donation on the body

In general, donating blood is harmless to the donor. Firstly, the amount of blood taken during donation is not critical for the functioning of the body, and it is restored quite quickly. Secondly, donors undergo a medical examination before donation. If doctors believe that donating blood may be harmful to the donor, he will be disqualified (i.e., no blood will be taken from him). The donor health requirements in Russia are extremely strict.

Donation is even considered useful. Thus, donors tolerate blood loss more easily, for example, after injuries or operations: their body is “trained” to compensate for the loss of some blood. Donors have healthier cardiovascular systems and, on average, a lower risk of heart attack. Donors regularly undergo medical examinations, which means they can promptly learn about any deviations from the norm and take action.

Adverse consequences from donating blood and its components

However, the body’s recovery after blood donation does not occur instantly.

The main adverse effect of donating whole blood is the loss of red blood cells and, consequently, a decrease in hemoglobin levels. If you are prone to anemia, it is not recommended to donate blood. But, in principle, this is clarified even before donating blood, when the donor is given a rapid test for hemoglobin: the norms for hemoglobin are very strict, and if its level is even one unit lower than required, then the blood will not be taken.

Platelet levels usually recover fairly quickly after plateletpheresis. But some problems may be associated with the use of sodium citrate. This substance prevents donor blood from clotting during platelet donation; it speeds up and facilitates the apheresis process. But the disadvantage of using citrate is that it binds calcium, and there is a risk of “leaching” calcium from the bones. Therefore, when donating platelets, the donor is given an injection of calcium gluconate several times, and after it it is recommended to drink calcium-containing vitamins for a while (Calcium D3 Nycomed, Calcium Vitrum). You can simply take calcium gluconate tablets with lemon juice. In addition, regular donors are advised not to donate platelets too often - say, once every two to three months. This is also associated with the risk of the so-called citrate reaction: after numerous frequent plateletpheresis, the body begins to poorly tolerate the entry of new doses of citrate into the blood, which is manifested by a deterioration in well-being during and after donating platelets.

Granulocyte donation

Granulocyte donation is a newer and rarer procedure in transfusiology, and so far the effect of granulocytapheresis on the health of the donor has not been studied in much detail. Some donors are concerned about the use of Neupogen for bone marrow stimulation. But doctors believe that a single use of this stimulant does not lead to negative long-term consequences for the body, although research on this topic is constantly being conducted. Thus, the journal Transfusion (March 2010 issue) analyzed data on the health status of donors who more or less systematically donated granulocytes about ten years ago; Compared to the control sample, they did not show a significant tendency towards the occurrence of any diseases, including cancer.

For some time after granulocytapheresis, you may experience slight bone pain or a cold-like malaise, but these unpleasant phenomena are a normal reaction of the body to bone marrow stimulation and pass quickly. More serious complications are extremely rare. Citrate is not used during granulocytapheresis (it is replaced with heparin), so there is no problem of calcium leaching.

Why should I donate blood? Aren't there enough donors already?

In Russia, only 1.7% of the population are donors.
In order to ensure an adequate supply of blood, it is necessary that at least 4% of the population be donors. Many people are not suitable for donation due to contraindications, since the blood must be safe for patients. Donors can only be healthy people over the age of 18. The Hematology Research Center is constantly in need of whole blood donors, plasma donors, platelet donors, and stem cell donors. The Center undergoes long-term treatment for cancer patients for whom blood and its components are vital. Without them, they simply will not be able to survive after immune-lowering doses of chemotherapy.

What is the state of blood donation now?

In Russia, there are less than half of the donors than there should be in order for the needs of hospitals to be covered. This is why it is necessary for donors to donate blood regularly. In addition to major tragic events (terrorist attacks, fires, etc.), there is a constant need in modern medicine for components and products of donor blood, because almost any area of ​​it now cannot do without the use of transfusion therapy (surgeries, hematology, emergencies, road accidents, women in labor, children, oncology and etc.).

Do I have enough blood to share?

An adult has 4-5 liters of blood. During blood donation, 450 ml of blood is taken - this accounts for 8% of all blood, which is restored within 72 hours. Drainage is completely safe and stimulates the immune and hematopoietic systems.

How long does the blood donation procedure take?

When you go to donate whole blood, expect 1 hour 10 minutes. This is how much time it will take you to fill out the form, undergo a medical examination, and rest after donating blood. Donating whole blood takes only 5-10 minutes.

If you donate plasma, you will spend 1 hour 40 minutes, including 40 minutes on the plasma donation procedure itself.

The entire process of donating platelets will take you 2 hours 30 minutes, including 1 hour 30 minutes for the donation itself.

How are donors selected?

All donors undergo a medical examination before each blood donation. At this time, a clinical analysis of capillary blood from a finger is carried out, a thorough interview with a transfusiologist, who reviews the questionnaire filled out by the donor and, based on the donor’s health condition and the results of the analysis, determines whether the person is suitable for donation. It is very important that the donor who fills out the questionnaire answers the questions asked objectively.

All information about the donor is confidential.

But there are well-known contraindications to donation, temporary and permanent, which we recommend that those wishing to become a donor familiarize themselves with.

Can I get a viral infection while donating blood?

Infection of a donor during blood donation is impossible, since his blood does not come into contact with the blood of another person, and during the procedure, disposable sterile needles and bags and blood collection instruments are used, which completely exclude the possibility of interaction of the donor’s body with the external environment.

The platelet donation procedure (plateletpheresis) uses a closed, disposable system where the plateletpheresis machine is charged immediately before each donor.

Only highly qualified medical specialists from the donor service with many years of experience work with donors.

Why do you need to rest after blood donation?

Each donor should rest for at least 10 minutes after donating. Even if you feel fine after donating, drink juice, tea, water or coffee. This helps replenish fluid loss in the body. If you feel weak after donating blood, the experienced staff at the donor service will be able to help you quickly.

I don't remember the last time I donated blood. How do I find out?

This information can be clarified at the donor department of the National Medical Research Center for Hematology on weekdays from 9:00 to 17:30 by phone:

What will they do with my blood?

The blood of each donor is thoroughly examined. First, the blood group according to the AB0 system, Rh and Kell affiliation are determined. This is necessary so that the patient receives the blood component that suits him. Testing for blood-borne infections and syphilis is then performed to ensure safe transfusion.

Whole donor blood is not used. Each dose of blood is divided into red blood cell suspension and plasma. The patient receives exactly the component he needs. Thus, the blood of one donor can save the lives of several patients.

Red blood cell suspension is used during routine operations, for blood loss, trauma, and to treat anemia.

Plasma is used for liver disease, blood loss, to treat blood clotting disorders, and to treat shock.

Is it possible to purchase (purchase) blood and its components from you?

Blood and its components cannot be purchased.

Blood taken from donors at the Hematology Research Center is used exclusively for patients of the Center.

Is there a blood substitute?

Blood is a unique organic material that cannot be artificially produced. The only source of blood is the donor.

What will I get for donating blood?

The donor who donated blood (components), first of all, will receive monetary compensation for food in the amount of 5% of the established subsistence level, 2 days off at the place of work (on the day of donating blood and any other day of his choice within a year after donation), and also high self-esteem from the knowledge that you have helped other people.

In addition, the donor will have constant monitoring of his health.

Is my employer required to let me go from work while I donate blood?

Yes, according to the Law of the Russian Federation “On the donation of blood and its components” dated July 20, 2012 No. 125-FZ and the Labor Code of the Russian Federation (Art. 186).

How often can you donate blood and its components?

There are different types of donation: whole blood donation and component donation.

Whole blood is allowed to be donated no more than 5 times a year for men and no more than 4 times a year for women, and the intervals between blood donations must be at least 60 days.

Certain blood components can be donated more often. The intervals between different types of donation of blood components are indicated in the table (read more).

When donating plasma, you are allowed to donate a total of no more than 12 liters of plasma per year.

As for plateletpheresis, the donor is allowed to donate platelets no more than once a month. This is due to the fact that the National Medical Research Center of Hematology uses hardware plateletpheresis, in which the dose of platelets taken at a time is greater than with intermittent (read more).

How is donating blood different from donating plasma and donating platelets?

When donating plasma, blood, after part of the plasma is separated from it, is immediately returned back to the donor’s body. When donating platelets, only platelets are separated from the donor blood, and the remaining components are returned to the donor.

Isolation of plasma and platelets from the blood occurs by passing donor blood through a special apparatus with a closed disposable centrifugation system.

Plasma can be donated at intervals of at least 2 weeks, no more than 12 liters per year, whole blood - no more than 5 times a year at intervals of 2 months, platelets - 12 times a year at intervals of 1 month.

After five regular blood donations, it is better to take a break for 3-4 months. Plasma is restored within a few days, blood within a month.

The process of donating platelets takes about 1.5 hours, plasma - about 40 minutes, blood sampling - about 10-15 minutes. However, the total time that the donor will need to spend in a medical facility will be 2.5 hours in the first case, 1 hour 40 minutes in the second case, and 1 hour 10 minutes in the last case.

Can a smoker be a donor?

Smoking is not a contraindication to donation. Experts recommend refraining from smoking an hour before the blood donation procedure and not smoking for one to two hours after donation.

What should you do to restore your body after donating blood?

On the day of blood donation, heavy physical and sports activities and heavy lifting are not recommended. There are no restrictions on driving a car on the day of blood donation.

For two days, it is recommended to eat well and regularly, drink at least 1-2 liters of liquid per day (alcohol is not recommended).

Then lead your normal lifestyle.

Complete restoration of blood composition occurs within 5-7 days. The rate of recovery of different blood components is different. To restore your blood composition faster, it is recommended to drink more fluids: juices, tea. Proper nutrition is necessary: ​​the donor’s diet should always contain protein, which determines the level of hemoglobin in the blood, as well as foods high in iron and calcium.

Do regular blood donors have to use their blood donation vacation days during the calendar year?

In accordance with Article 186 of the Labor Code of the Russian Federation, after each day of donating blood and its components, the employee is given an additional day of rest. The specified day of rest, at the request of the employee, can be added to the annual paid leave or used at other times during the year, after donating blood and its components.

In the previous version of this article, the employee’s right to use an additional day of rest after donating blood was limited to the calendar year (from January 1 to December 31), which infringed on the interests of donors. Moreover, in a number of cases, namely when donating blood in the last days of the calendar year, it was not possible to implement it.

In accordance with the amendments made to the Labor Code by Federal Law No. 90-FZ of June 30, 2006, the word “calendar” was excluded from Article 186. Thus, donors can use the additional day of rest they are entitled to within 365 days after donating blood.

Are the actions of an employer legal when it refuses to provide days to an employee-donor, citing the fact that he donated blood before he had yet joined the organization?

The legislation of the Russian Federation does not contain a direct answer to the question posed. On the one hand, the provision of unused additional days of rest provided for in Part 4 of Art. 186 of the Labor Code of the Russian Federation, for a new place of work (with another employer) is not provided for by law.

On the other hand, Art. 186 of the Labor Code of the Russian Federation does not in any way limit the donor’s right to use rest days only at the previous place of work, however, this position may lead to a labor dispute with the employer, which will have to be resolved in the bodies for considering individual labor disputes (Chapter 60 of the Labor Code of the Russian Federation).

How can I confirm my right to the title “Honorary Donor”?

Thanks to the unified donor registration system being created in our country, all donations are recorded in the databases of Blood Service institutions; the data must be stored there for many years.

Please note that to obtain the right to be awarded the “Honorary Donor of Russia” badge, only gratuitous donations are taken into account.

Is it possible to become an “Honorary Donor of Moscow”?

No, the “Honorary Donor of Moscow” badge is provided only by blood service institutions subordinate to the Moscow Department of Health. The Hematology Research Center is an institution subordinate to the Russian Ministry of Health, from us you can receive the “Honorary Donor of Russia” badge.

Is it possible to be a donor to a nursing mother?

Today, one of the temporary contraindications is the period of pregnancy and lactation. 1 year must pass after birth and 3 months after the end of lactation.

Can the presence of Kell (+) antigens in the blood become a disqualification for donation?

The presence of Kell (+) antigens in the donor's red blood cells does not mean that a person cannot become an active donor.

If such an indicator is present in the blood, he can be a donor of plasma and platelets.

Read more about Kell accessories at this link.

Is it possible to become a donor if a close relative has inactive chronic hepatitis B?

In this situation, the person is a contact person with a hepatitis patient and must be exempted from donation.

What causes a citrate reaction?

When donating platelets, in order to avoid blood clotting when it passes through a centrifuge to separate platelets and plasma from it, sodium citrate (sodium citrate trisubstituted 2-aqueous) is used.

The citrate reaction is the body's reaction to intolerance to sodium citrate.

Therefore, regular platelet donors should try to donate platelets once every two to three months, as well as take calcium vitamins after donation and follow nutritional recommendations (read more).

Chylosis is a blood disease?

Chylosis is not a disease, but a condition that indicates the presence of triglycerides in the blood - fatty particles (neutral fats) that do not allow for an accurate diagnosis. Normally they should not be in the blood. After centrifugation, such blood becomes white and very thick, resembling sour cream in appearance.

The reason for the high level of neutral fats and the formation of chylous serum is improper preparation for blood collection, when alcohol or fatty foods are consumed by the donor before donation.

Chylous serum does not make it possible to isolate blood components. Therefore, a blood test cannot be performed. It is also impossible to use “fat” blood for transfusion to the recipient.

After 10-12 hours, the level of triglycerides in the blood decreases to the initial level.

Find out how to feed your donor properly.

How long after donation can workers in hazardous industries return to work?

If you work in a hazardous industry, the interval between donation and going to work should be at least 12 hours.

Can donations for which compensation for food were paid be considered gratuitous? Will they be considered for the Honorary Donor designation?

All donations after which you received only monetary compensation for food will be taken into account when receiving the “Honorary Donor of Russia” badge.

Donors who donate blood and/or its components (except for blood plasma) 40 or more times or blood plasma 60 or more times are awarded the “Honorary Donor of Russia” badge.

Also, amendments introduced by Article 61 of the Federal Law of November 25, 2013 No. 317-FZ “On amendments to certain legislative acts of the Russian Federation and invalidation of certain provisions of legislative acts of the Russian Federation on issues of protecting the health of citizens in the Russian Federation” to Article 23 of the Federal Law dated June 20, 2012 No. 125-FZ “On the donation of blood and its components”, established the most optimal formula for calculating quantitative criteria for achieving the right to award in cases of mixed donation.

Now, if a donor has, for example, twenty-five or more free donations of whole blood behind him, and then began donating plasma free of charge, the right to an award will come with a total number of donations of 40 times.

If a donor has switched to the category of plasma donors, having previously donated whole blood less than 25 times free of charge, then in order to receive the right to be awarded, he will need to continue to donate free plasma until he reaches a total number of donations of 60 times.

The law stipulates that the donation of any cellular component (erythrocytes, platelets or granulocytes) is equivalent to the donation of whole blood. Read more.

Memo to the donor

BLOOD is living medicine. When it is transfused, the protective forces and metabolic processes in the patient’s body increase. The uniqueness of blood lies in the fact that, despite the achievements of modern science, it is INDISPENSABLE. And its only source is a healthy person - a DONOR.

ONLY ONE PERSON'S BLOOD CAN SAVE ANOTHER PERSON'S LIFE

Trouble comes unexpectedly and you need to be prepared for it in advance. Sometimes the patient’s life is counted down to minutes, and a lack of donor blood can lead to irreparable consequences. In order for assistance to be timely, the Blood Center must constantly have and maintain a sufficient supply of donor components and blood products. If the Blood Center has enough donors who donate blood regularly, then everyone can be sure that in the event of illness or injury, the necessary blood products will be available.

ABOUT THE BENEFITS OF DONATION

The human body has great compensatory capabilities and quickly restores the complex of substances and cellular elements lost during blood donation. At the same time, donors maintain good health, mood and ability to work.

Among donors, diseases of the cardiovascular system are 9 times less common than among those who are not used to sharing their blood.
Periodic blood donations have a beneficial stimulating effect on the donor’s body and provide a rejuvenating effect. By donating blood, you are constantly monitoring your health!
RULES FOR SAFE DONATION

Donating in a modern blood center is an absolutely safe process for healthy people, and yet it requires compliance with a number of simple but very important rules, which we have compiled for you in a special reminder. By following them, you can avoid unwanted reactions after donating blood. We recommend that you review this leaflet every time you donate blood.

What you need to know about platelets and bruises

Falls and blows lead to bruises and abrasions. The body has powerful defenses in this case, stopping bleeding and resolving hematomas (bruises). The number of bruises is related to physical activity. Problems arise if there is a lack of coordination. Then even simple exercises and movements end in injury and hematoma.

The harder the blow, the bigger the bruise

If you cannot connect the blow and the appearance of a bruise, look at your shins, where the elastic of the socks ends. If there are small red spots that do not disappear with pressure, or bruises, this is a reason to be examined further.

The appearance of bruises, even with a minor injury, at the site of compression by an elastic band (from socks, panties, a belt, etc.) is called increased bleeding (hemorrhagic syndrome). Pay attention to complaints such as frequent nosebleeds, bleeding from the gums, and prolonged heavy menstruation in girls.

In mild cases, there is always an explanation: inflammation of the gums, hormonal imbalance, previous infection, and even stories that “in our family all the girls have heavy menstruation,” “and our dad also always has bruised legs,” etc. .

But not everything is so rosy. Severe hemorrhagic syndrome often ends in massive bleeding that threatens life. All of the above may be a manifestation of diseases combined into the group of thrombocytopathies - platelet pathologies.

What are platelets

Platelets are small platelets of blood produced in the bone marrow. Their purpose is to protect the walls of blood vessels in case of damage. Being able to stick to each other, platelets form a plug at the site of the wound and prevent blood from flowing out of the damaged vessels. In some congenital or acquired diseases, platelet production is reduced and thrombocytopenia (low number of platelets in the blood) develops; in some cases, platelets are born with defects, which is called thrombocytopathy.

The shape and properties of platelets suffer in many diseases: liver disease, scurvy (vitamin C deficiency), B12 deficiency anemia, hypothyroidism (thyroid deficiency), due to the action of drugs (aspirin and a group of non-steroidal anti-inflammatory drugs, some types of antibiotics and other).

What to look for in a blood test

A complete blood count is the first test that is done if defects and a decrease in platelets are suspected. Typically, venous blood is collected in a tube containing the anticoagulant EDTA (purple cap), which prevents the blood from clotting and allows cell counting.

The automatic blood analyzer determines the following platelet parameters:

• Platelets, PLT - the number of platelets per unit volume.
• Mean platelet volume, MPV reflects the value of the mean platelet volume. A very important parameter in detecting thrombocytopathy (small, normal or large platelets).
• The indicator of platelet distribution by volume, PDW, reflects what percentage of platelets has a volume different from the bulk.
• Thrombocrit, PCT is an additional test that reflects the ratio of platelet volume to blood plasma, depending on their number and volume.

What is a “manual platelet count”?

Platelets behave harmfully not only in the body, but also in a test tube with venous blood. Because they know how to stick together and form small balls (conglomerates). This leads to false thrombocytopenia, the inability to detect defective platelets in an automatic analyzer, etc. Often, a general blood test must be repeated several times, blood must be collected in a test tube with a different filler, and a blood smear must be prepared and stained for “manual counting” and visual assessment of platelets under a microscope. This, like other specific tests for the properties of platelets, can be done in laboratories at hematology centers.

What to pay attention to:

• Presence of bleeding during teething/changing or extraction;
• Bleeding gums when brushing teeth;
• Presence of nosebleeds;
• Amount of menstruation in girls;
• Bleeding after surgical interventions (removal of adenoids, tonsils and others);
• The presence of similar symptoms in close relatives.

First tests for excessive bleeding

• Complete blood count with platelet count and determination of platelet indices
• Prothrombin index, prothrombin time, INR

In our Lab4U laboratory, tests can be taken at a discount of up to 50%, for example, a set of tests for increased bleeding.

In accordance with the “Federal clinical guidelines for the diagnosis and treatment of thrombocytopathies in children and adolescents.” Public organization National Society of Pediatric Hematologists and Oncologists; FSBI "FNKTs DGOI im. Dmitry Rogachev" of the Russian Ministry of Health. – Moscow, 2015.

How does donation affect the health of the donor?

“Maximum benefit to the patient - no harm to the donor” - this principle is strictly observed by the Blood Service employees.

Donation does not harm the body if the person is healthy. Procuring blood from a donor is permissible only on the condition that his health will not be harmed. In this case, the volume of one donation should not exceed 12% of the circulating blood volume, which normally amounts to 6.5-7% of body weight. The standard volume of blood collection (donation) of 450 ± 50 ml, excluding the amount of blood taken for tests (up to 40 ml), for persons weighing at least 55 kg, ensures the safety of the health of the blood donor.

Each blood loss in a standard volume causes a number of changes in the donor’s body: the hemoglobin level decreases (within 5 days after donation by 2-10% compared to the initial value), the number of red blood cells decreases (from the first hours after blood collection and over the next 5 days ).

Complete restoration of blood composition occurs within 40-50 days. The rate of recovery of different blood components (plasma and blood cells) is different. Red blood cells are restored in the donor's body within 4-6 weeks, and leukocytes and platelets - by the end of the first week, plasma composition - within 1-2 days, hemoglobin level - within a month. It has been proven that in people who have given blood multiple times, the restoration of peripheral blood parameters occurs faster than in primary (donating for the first time) donors. This is explained by the “training” of the hematopoietic organs through repeated bloodletting.

To restore your blood composition faster, it is recommended to drink more fluids - juices, tea. The donor's diet should always contain protein, which determines the level of hemoglobin in the blood (foods containing protein: meat, beets, buckwheat, lentils, beans and all legumes, fish, etc.).

The reaction to blood collection varies from person to person. It depends on many factors: psycho-emotional state, physical activity, nutrition, living conditions of donors, weather conditions.

The loss of a standard blood volume is accompanied by changes that have a dual origin. Immediately after giving blood or in the next few hours, a so-called stress reaction develops to the situation and the blood collection procedure, depending on the type of nervous system and hormonal characteristics of the donor, and a reaction to the loss of cells and substances contained in the blood. Immediately after taking blood from donors, changes in some hemodynamic parameters are observed: a decrease in venous and blood pressure, acceleration of blood flow, and a slight increase in heart rate. The reaction to blood loss is short-lived; normalization of cardiovascular activity occurs within 30-60 minutes. During this period, donors are advised to rest.

After donation, some donors may experience a slight decrease in muscle strength, as well as an increase in the percentage of errors when solving test mathematical and logical problems. This indicates changes in the regulatory mechanisms of the nervous system, which affects work activity. In this regard, donors whose work is associated with great emotional stress and requires quick and accurate reactions (for example: transport drivers, crane operators, high-altitude workers, etc.) are not recommended to start it immediately after donating blood.

For any healthy adult, the process of donating blood is safe and does not harm the body. Repeated blood draws have a beneficial effect on the central nervous system, and through it on the metabolic processes of the entire body. According to a study by Finnish scientists, men who donate blood are ten times less susceptible to myocardial infarction and coronary heart disease; data from American researchers confirm that male donors suffer 30% less from cardiovascular diseases; Regular blood donation maintains cholesterol levels at the proper level, which, in turn, ensures prevention (prevention of the development) of atherosclerosis.

Those who donate blood regularly have a better chance of surviving extreme situations such as road accidents, burns, and major surgeries. The body of a donor who regularly donates blood and its components quickly activates the hematopoietic system during blood loss, which contributes to a speedy recovery. In addition, donors’ blood is renewed more often, “old” blood cells are eliminated, and donors, according to the World Health Organization (WHO), live on average 5 years longer than those who do not donate blood.

Donation of blood and its components is useful for the prevention of diseases of the gastrointestinal tract (stomach, intestines, pancreas, liver), metabolism and diseases of the immune system, which is associated with the renewal of the body and activation of the immune defense.

• Sit quietly for 10-15 minutes and, if you feel well (do not feel weak or dizzy), go to the buffet and drink sweet tea.
• If you feel dizzy, contact your medical staff. The easiest way to help yourself is to lie down and raise your legs above your head, or sit down and lower your head between your knees. Never try to walk or drive a car if you feel dizzy!
• Do not remove the bandage for 3-4 hours and try not to get it wet. This will protect you from bruising (if a bruise appears, apply a bandage with heparin ointment and/or troxevasin at night).
• Avoid heavy physical and sports activities, lifting heavy objects, including shopping bags, on this day.
• Eat well and regularly for 2 days after donation and drink at least 2 liters of liquid per day: juices, water, weak tea (alcohol is not recommended).

1) Who can become a blood donor.

A person who is 18 years old on the day of donation can become a donor. There is no upper age limit if a transfusiologist at a blood service institution, based on the results of a medical examination, decides on admission to donation. The donor must present at the institution a passport of a citizen of the Russian Federation, as well as SNILS. Foreign citizens can donate blood if they have resided legally in the Russian Federation for at least a year (supporting documents must be provided). The standard blood collection volume is 450 ml + 10% for analysis (up to 40 ml), which is recommended for donors weighing over 55 kg. The decision on admission to donation and the type of donation is made by a transfusiologist at a blood service institution based on the results of a medical examination. Medical examination of donors contains a procedure common to all types of donation and categories of donors and additional individual requirements for each type of donation and categories of donors. Work with donors and medical examination of donors are carried out in full compliance with the Federal Law “On the Donation of Blood and Its Components” {↑}

2) What documents must the donor present?

To perform the donor function, the donor is required to present a passport of a citizen of the Russian Federation or another identification document. With an identification document, the donor must present SNILS once. Please note that photocopies, electronic versions of documents and other types of documents other than originals are not accepted. Identity documents of a universal nature are here. For foreign citizens, we note that, together with an identity document of a foreign citizen, a person must present documents confirming residence in the territory of the Russian Federation legally for at least one year. {↑}

3) How to prepare for donation.

Taking medications: antibiotics - donation is possible no less than 14 calendar days after the end of the dose. Analgesics, anticoagulants, antiplatelet agents (including salicylates) - donation is possible no less than 3 calendar days after the end of administration. 48 hours before donation, it is not recommended to consume alcoholic beverages, fatty, fried, spicy and smoked foods, as well as dairy products, eggs and butter, chocolate and dates. In the morning, it is recommended to have breakfast in compliance with the “donor diet”. Before blood donation you need to rest. It is not advisable to donate blood after a night shift, heavy physical work, nervous strain, or prolonged food restriction.

Possible options for the first breakfast: Oatmeal porridge with water, boiled beef tongue, tea with sugar, toasted bread and porridge with water, chopped fresh vegetables, cereal with water with the addition of dried fruits.

Possible options for second breakfast: Fresh fruits (except those in the NO category), freshly squeezed juice, dried fruit compote, jelly, soaked dried apricots, mineral water, fruit juice, drying.

Possible lunch options: Vegetarian vegetable soup, boiled chicken breast, noodle soup, rice, buckwheat, pearl barley soup, boiled noodles, meat balls or boiled fish without marinade, warm salad to taste without dressing.

Possible dinner options: Carrot zrazy, mashed potatoes (in water), low-fat fish (baked in the oven without marinade, boiled potatoes, steamed meat cutlets, vegetable salad without dressing, potato casserole with meat, grated carrot salad with apple without dressings, steamed fish balls, boiled potatoes with herbs, sweet bell peppers, carrot and apple balls, boiled low-fat fish without dressing and sauces, vegetable stew, stewed cabbage, steamed vegetables, water pasta.

Not allowed: Smoked, spicy and fried foods, pickles, dairy products (including yoghurt, cheese, cream, butter), eggs, nuts, dates, bananas, beets, blueberries, sausages, halva, seeds, snacks (chips, croutons) etc.), ketchup, mayonnaise, sauces and marinades, fatty meats or fish.

Such dietary restrictions are due to the fact that many products contain harmful synthetic substances that help the products retain their taste, color and freshness for a long time. Also, consuming even a small amount of fats and animal proteins affects the composition and quality of the blood, and interferes with its separation into components. In addition, due to microparticles of fat, the blood serum becomes too thick, viscous, and takes on a cloudy appearance called plasma chylosis. We will determine dietary violations before and/or during donation. Violations in the diet lead to changes in the quality of blood and its components. A donor who violates the diet is suspended from donations for a certain period of time {↑}

4) What diseases should you not donate blood for?

There are certain medical temporary and absolute contraindications to donating blood and its components, a full list of which is available here. You may be disappointed that you will not be able to donate if you have persistent contraindications. However, the Blood Service hopes that you will understand our main goal - ensuring the safety of donated blood components for patients. The presence of contraindications to donation does not mean that you cannot contribute to the development of voluntary blood donation! In the volunteer section you can find out how to help the donor movement. Save lives with the Blood Service! {↑}

5) Where and when can you donate blood.

The city blood transfusion station accepts donors on weekdays from 09:00 to 13:00 and the first Saturday of the month from 09:00 to 13:00. Sunday: no donors are accepted. Additional weekends and holidays are established according to the production calendar. Restrictions on admission are possible based on the needs of the institution and requests from medical organizations in St. Petersburg. Current admission information is published here. We recommend visiting our website or VKontakte group on the eve of visiting the station to familiarize yourself with possible restrictions and the data of the current Donor traffic light. You can ask your question to the institution’s specialists via the WhatsApp messenger. The city blood transfusion station is located five minutes from the Moskovskie Vorota metro station (map). There may be restrictions on accepting primary donors, i.e. those who have not previously passed in our institution. In the section “Where to donate blood in St. Petersburg” you will find contact information for all blood service institutions in the city. We recommend contacting your chosen institution before visiting. {↑}

6) Possible restrictions on accepting donors.

It is impossible to predict the need of hospitals for donor blood of a particular blood group and Rh factor. It is unknown how many patients and with what blood group will require donor blood transfusion. Situations arise when there is not enough blood of a certain group and rhesus, and there is an excess of another. To create an optimal supply of donor blood, a “Donor traffic light” was created. A special section provides information about accepting donors and which blood groups are in demand and which are in full supply. Why is personnel donation so important and why are there restrictions on admission? Whole blood taken from a donor is divided into components: red blood cells, platelets and plasma. But red blood cells and platelets cannot be stored for long and must be transfused soon after donation. But blood plasma (in the presence of infections, it is this that contains the bulk of viruses!) can be preserved, and this property is used for additional prevention of infections. 4 months after donating, the whole blood donor must return to the institution where he donated and donate whole blood, one of the blood components, or simply a test for HIV and viral hepatitis pathogens. And only if all repeated tests of the donor 4 months after blood donation again show the absence of infections, his plasma will be transfused to patients in need. This storage of plasma until the donor is retested is called quarantine. It is precisely because of quarantine that it is very important that the donor comes back to the blood service institution a certain time after giving blood. This is especially important to know for donors who come to donate blood for the first time after major disasters, accidents, or terrorist attacks. As a rule, on such days a lot of people come to the blood transfusion station, but after six months the enthusiasm has already evaporated and donors forget about the need to come again. Please remember her! If a donor makes donations on a regular basis (at least twice a year), then each of his donations is an analysis of the previous donation, which was made 4 months ago. {↑}

7) How does the donation procedure work?

Point No. 1 - registration. At the registry, the donor provides a passport of a citizen of the Russian Federation and SNILS, and after checking in the information databases, our specialist draws up a card and gives the donor a questionnaire in which he must indicate information about his state of health and lifestyle. Try to answer all questions as truthfully as possible to ensure the safety of you and our patients. A donor who deliberately concealed or distorted information known to him about the state of health when performing a donor function bears liability established by the legislation of the Russian Federation if such actions resulted or could result in harm to the life or health of recipients.

• You can save your time at the institution - fill out the donor form and 3 informed consents and come with the completed documents. The file can be downloaded here. It must be completed legibly with your own hand (in block letters in black or blue ink). Consents filled out in the wrong form will not be accepted.

Point No. 2 - laboratory for rapid blood finger test. The donor takes a finger prick blood test in the laboratory, this is necessary to determine the donor's hemoglobin level, as well as other blood factors. The results of this analysis determine whether a person can become a donor on that day.

Point No. 3 - transfusiologist. The doctor examines the donor, studies the questionnaire, and asks additional questions about health, lifestyle and habits. The doctor examines the results of a finger prick blood test and makes a decision on whether to allow donation. The doctor complies with the rules of medical ethics: the information received from the donor is subject to medical confidentiality. An examination by a doctor and a conversation between a doctor and a donor are mandatory procedures before donating blood or its components. Do not hide your ailments from the doctor, answer his questions and the questionnaire honestly, and then donation will be safe both for you and for those who need a transfusion of blood or its components. We remind you that the final decision on the donor’s admission to the procedure, as well as determining its type and volume, is made only by the transfusiologist of our institution. If, during the examination of the donor and the collection of his medical history, assessment of general health, as well as the associated lifestyle, there is a suspicion of drug addiction or behavior leading to the risk of contracting infectious diseases transmitted by blood, the donor should be diverted from donating blood and its components . When determining admission to donation, type of donation and volume of blood or its components taken, the doctor is guided by the List of contraindications to donation of blood and its components, Standards for the composition and biochemical parameters of peripheral blood, Intervals between types of donation (in days). In case of medical withdrawal, the transfusiologist explains to the donor the reason and duration of the withdrawal. If there are temporary contraindications, any visible health problems are detected, or contact with an infectious disease is suspected, the donor is sent for examination to an outpatient clinic at the place of residence.

Point No. 4 - rest and tea before donation. Before donating blood, the donor is asked to eat before the procedure. To balance fluid in the body, it is recommended to drink more, for example, water or weak tea with cookies or a bun. We offer our donors delicious sweet tea and fragrant cookies =)

Point No. 5 - donation. The donation procedure is carried out in the most comfortable conditions for the donor. Blood is collected in specialized sterile and closed systems.

Point No. 6 - compensation for food and rest days. After donation, each donor is issued a certificate, which gives the right to certain benefits and privileges (Read in the “Documents for Donors” section). The donor also receives lunch or compensation for food in order to regain strength after donating blood or its components. Read more about power compensation below.

Social support for donors.

Rest days. After donating blood, the donor receives a certificate that gives him the right to 2 days off during the calendar year from the date of donation (Article 186 of the Labor Code of the Russian Federation). Full text of explanations for the employee and employer with all references to legislative acts.

Nutrition compensation. In accordance with regulatory legal acts, a gratuitous blood donor is paid monetary compensation for food in the amount of 5% of the subsistence minimum established for residents of the city of St. Petersburg (as of June 2021 - 654 rubles). City institutions, in accordance with regulations, pay a gratuitous blood donor monetary compensation for food in the amount of 5% of the cost of living established for residents of the city of St. Petersburg (as of June 2021 - 654 rubles), as well as in accordance with Chapter 12 of the Law of St. -Petersburg “Social Code of St. Petersburg” we make an additional one-time payment for food to a donor who has confirmation of permanent residence in St. Petersburg (as of June 2021 - 814 rubles).

Summarizing this point, we give a short conclusion: any donor in federal and departmental clinics receives compensation for food in accordance with federal law (as of June 2021 - 654 rubles), and a donor who donates blood in city institutions (including at the City Blood Transfusion Station ) and having permanent registration in St. Petersburg, receives food compensation in accordance with federal law (as of June 2021 - 654 rubles) + additional payment in accordance with the “Social Code of St. Petersburg” (as of June 2021 - 814 rubles). Based on the Law of St. Petersburg “Social Code of St. Petersburg”, additional measures of social support for donors in the form of an additional one-time payment for food are paid to donors who confirm their place of residence or place of stay in St. Petersburg with the provision of a document issued by the registration authorities ( temporary or permanent registration). Please note that food compensation is not payment for blood. With the funds received, the donor must replenish his strength, namely, eat more and drink more fluids.

Social support for donors is provided in full compliance with the Federal Law “On the Donation of Blood and Its Components” and the Law of St. Petersburg “Social Code of St. Petersburg” {↑}

9) Rest periods between donations.

The frequency of donation depends on gender, type of donation and doctor’s recommendations. Whole blood is allowed to be donated no more than 5 times a year for men and no more than 4 times a year for women, and the intervals between blood donations must be at least 60 days. When donating plasma, you are allowed to donate a total of no more than 16 liters of plasma per year. As for plateletpheresis, an interval of 2 weeks between platelet donations is allowed. The blood service institution reserves the right to increase these intervals depending on the needs of medical organizations for certain components of donor blood. The final decision on the types of donation and the rest period is made by the doctor at our institution. {↑}

11) Who are Kell+ donors?

The Kell system is a blood group system that includes 25 antigens, including the most immunogenic after A, B and D, antigen K. Based on the presence or absence of K antigen in red blood cells, all people can be divided into two groups: Kell- negative and Kell-positive. The presence of antigen K (Kell-positive) is not a pathology and is inherited, like other human group antigens. In Russia, it occurs in 7-10% of residents. Currently, blood service institutions determine the presence of antigen K, as the most dangerous for the occurrence of immunological complications. Many cases of blood transfusion complications and hemolytic disease of newborns have been described, the cause of which was isoimmunization with the K antigen. Kell-negative patients should receive only blood from donors who do not have the K antigen to prevent hemolysis. Kell-positive individuals are universal recipients of blood, since they do not experience rejection of its components. “In order to prevent post-transfusion complications caused by the K antigen of the Kell system, departments and blood transfusion stations issue red blood cell suspension or mass that does not contain this factor for transfusion into medical institutions.” (Order of the Ministry of Health No. 363 of November 25, 2002). You can find out about the possibility of donating KELL-positive blood yourself on the page of blood service institutions. {↑}

12) Donation of platelet cells.

Thrombocytapheresis (platelet donation) is a procedure for removing platelet cells from a donor’s blood. Platelets are blood cells responsible for blood clotting. The speed of stopping bleeding in children with cancer, women after difficult births, and patients with bleeding disorders depends on their quantity. The plateletpheresis procedure takes from 1 to 1.5 hours. Platelets are prepared according to requests from medical organizations (by appointment via phone 635-68-85 or messengers). If there are no requests for platelets, the donor will be offered a whole blood donation if the rest interval between donations is observed. In accordance with regulatory legal acts, platelet donation is equal to blood donation and, based on the possibility of more frequent platelet donation, people performing this gratuitous donor function receive the titles “Honorary Donor of St. Petersburg” and “Honorary Donor of Russia” faster.

The doctor’s confidence in the donor’s candidacy should be maximum. This is associated not only with the risk of complications for the recipient, but also with the high price of consumables and large time costs for medical personnel and the donor. We urge you to review all of our recommendations and prepare responsibly for each platelet donation. The importance of platelet procurement is due to the relatively short “life”: the next day after donation, a fully examined dose of donor platelets must be delivered to the medical institution that submitted the application. Platelets are procured only upon request and cannot be procured for future use. Recently, the number of high-tech operations using donor platelets has increased and for this reason the need for this blood component is growing. Platelet donation is a noble and difficult mission, but very necessary for those who, for medical reasons, need one-time or regular health support and further recovery. Platelet donors are the golden fund of the blood service, because the help of this category of donors may be needed at any moment and there is no time to delay!

• During the meeting, the doctor at the City Blood Transfusion Station will provide information on how to properly donate platelets, as well as how to prepare for the procedure. Failure to comply with its requirements is fraught with blood clotting disorders, a decrease in platelet levels and, as a result, temporary exclusion from donation. You can learn more about platelet cell donation during your next visit to the City Blood Transfusion Station. You can ask questions to transfusiologists or the head of the department of donor recruitment, Elena Mikhailovna Kachurina. {↑}

13) Donor code for the application and donor’s personal account on the website yadonor.ru

What is a donation code? The donation code is a unique 20-digit code that is generated by the automated transfusiology information system and contains information about your donation displayed in the information base.

Where can I get a donation code? You can receive a donation code by contacting the reception of the City Blood Transfusion Station or the specialists of the institution’s visiting team after making at least 1 (one) donation. ATTENTION! In the case of donation in an off-site setting (on-site team), the code can initially be obtained only at the second donation. The code is issued once in printed form or as an SMS. The code can be sent to the donor via SMS when contacting the institution’s specialists with the following information provided: full name (full name), date of birth (full), mobile phone number. If the mobile phone specified in the system differs from the mobile phone indicated in the donor’s message, the donor must contact the institution in person with a passport to receive a code and enter current data into the system.

Why does the code give an error? Please note that it may take up to 24 hours from the time you receive your donation code to be activated for access to your Personal Account. The results of a complete laboratory test will be available no earlier than 48 hours after the complete donation. If more than 24 hours have passed since receiving the code, but it is still inactive, we recommend contacting technical support

14) Why is it important to donate blood and/or its components regularly.

In recent years, about 70% of Russia's donor potential consists of donors who donate blood repeatedly and repeatedly. The blood of this category of donors is the safest in terms of the transmission of infectious diseases due to regular examination and monitoring of the health status of personnel donors. People who regularly come to the Blood Service institution in the future receive the titles “Honorary Donor of St. Petersburg” and “Honorary Donor of Russia”.

And the most important thing. Help is never one-time. The future of the Blood Service lies with professional donors. Donate blood regularly. Come to the blood transfusion station at least twice a year. The importance of repeat donation is due to the fact that blood plasma is not transfused immediately, but first undergoes a quarantine procedure: it is deep frozen and stored for 6 months. If, after this period, the donor comes again and no infections are detected in his blood, then the first portion of his frozen plasma is sent to medical organizations for transfusion to patients, and the fresh one is quarantined. This measure allows you to avoid a blood transfusion from a person who may already be infected, but does not yet know about it, and laboratory tests have not yet shown the presence of dangerous pathogens in his body; the virus is either blocked by antibodies, or there is still too little of it. For example, for HIV infection this period ranges from 3 weeks to 3 months, for viral hepatitis B – 37-81 days. This period is called the seronegative “window” and lasts up to 4 months, after which infections begin to show up in blood tests. If for some reason you cannot visit our station after 4 months to donate blood again, please come just to get tested. The cost of your time will be small, and quarantined plasma, which is extremely necessary for maternity hospitals and children's institutions, will be distributed to medical institutions on time. If a donor does not come to the donor site a second time within a year, his blood, which has been quarantined, will be virus inactivated. {↑}
