rules that are important for a pregnant woman to know when taking tests

How to prepare for a general blood test?

A complete blood count (CBC) is most often taken by expectant mothers. At the beginning of pregnancy and at the 30th week - mandatory. Additionally, OAC is given at intervals of 1-2 months, if the doctor needs to learn more about the health status of his patient. Blood is taken for a general analysis usually from a finger. Sometimes - from a vein.

Preparing for the procedure is simple. The day before the test, you need to exclude all fatty and fried foods from food. It is advisable to avoid protein foods. It is best to have vegetables for dinner. If you take the test not early in the morning, but closer to lunch (in some clinics tests are taken until 14:00), you can have breakfast. The main thing is that at least 4 hours pass after eating. 2 hours before the analysis, but no less, you are allowed to drink clean still water.

rules that are important for a pregnant woman to know when taking tests

During a normal pregnancy, a number of changes occur in the activities of various organs and systems of the female body. For example, the volume of circulating blood increases by 30-40%. The level of plasma proteins decreases, causing a decrease in plasma pressure, which is why pregnant women are prone to edema. The total number of leukocytes (white blood cells) in pregnant women increases slightly, reaching a maximum at 30 weeks of pregnancy, and ESR (erythrocyte sedimentation rate) increases sharply. The number of platelets approximately doubles, and in the third trimester decreases slightly due to an increase in their consumption. Mean arterial pressure decreases slightly in the second trimester of pregnancy, but increases in the third, facilitating the flow of oxygen from mother to fetus. Oxygen consumption increases. Pregnant women experience dilation of blood vessels in the skin, as a result of which the woman feels less cold and can sometimes feel worse in hot weather. In the first and second trimesters of pregnancy, renal blood flow increases, but by the time of birth it gradually returns to its original level. Urine production increases by 50% and returns to normal only after childbirth. The body's energy requirement increases, and a pregnant woman on average needs about 2300 kcal per day (with 1500 kcal on average outside pregnancy). Considering all of the above, the expectant mother needs to register with the antenatal clinic in a timely manner and undergo regular tests in order to timely identify and evaluate the changes occurring in the body. This will make it possible to prevent the development of pregnancy pathology and correct the condition in the early stages, without resorting, if possible, to hospitalization. But tests will become a valuable source of information only if you prepare for them correctly. Laboratory blood tests General blood test. The study is performed in the morning on an empty stomach. Taking into account the daily rhythms of changes in blood parameters, samples for repeated studies are taken at the same time. Blood chemistry. A mandatory requirement is a complete abstinence from food on the morning of the test (a light dinner is recommended in the evening of the previous day). Intense physical work is contraindicated; stressful situations should be avoided. The influence of various medications on the biochemical parameters of the body is so diverse that it is recommended to stop taking medications before donating blood for testing. If discontinuation of the medication is not possible, it is necessary to inform the attending physician about what substances were used for therapeutic purposes; this will allow for the introduction of a conditional correction to the laboratory test results. During this analysis, many quantitative blood parameters can be examined - for example, such as determining the level of uric acid, studying the exchange of bile pigments, determining the level of creatinine and performing the Rehberg test, etc. Determination of the level of uric acid. In the days preceding the study, it is necessary to follow a diet: avoid eating foods rich in purines - liver, kidneys; Limit meat, fish, coffee, tea as much as possible in your diet. Physical activity is contraindicated. Study of bile pigment metabolism. Includes determination of the amount of bilirubin in the blood. For this purpose, blood serum is used. It is not recommended to take ascorbic acid before the study; It is also necessary to exclude medications or foods that cause artificial coloration of the serum (carrots, oranges). Determining the level of creatinine and performing the Rehberg test is carried out simultaneously in the blood and urine. To determine the level of creatinine, 24-hour urine is used. During the Rehberg test during an inpatient study, the pregnant woman should remain in bed and not eat before the study. On an outpatient basis, in the morning a woman drinks 400-600 ml of water and empties her bladder; time is recorded. After half an hour, 5-6 ml of blood is taken from a vein to determine creatinine. Another half hour after this (an hour after the first urination), urine is collected and its volume is determined. In case of insufficient diuresis (small amount of urine), urine is collected 2 hours before, and blood is taken an hour after emptying the bladder. Glucose tolerance test (“sugar load”). It is carried out only if there are preliminary results of determining glucose on an empty stomach, without load. A one-hour glucose tolerance test is recommended for all pregnant women at 24-28 weeks. The need for screening at an earlier stage (16-20 weeks) may arise in those pregnant women whose immediate relatives suffered from diabetes mellitus, as well as in patients with persistent glucosuria (presence of sugar in the urine), obesity and in the presence of gestational diabetes mellitus during a previous pregnancy. diabetes, macrosomia (large fetus), or unexplained intrauterine fetal death. When performing a one-hour test, there is no need to avoid eating the day before, but after taking 50 g of glucose orally, the woman should not eat for an hour until venous blood is drawn. When the glucose concentration is 7.7 mmol/l or more, the test is considered positive; in this case, a standard (3-hour) oral glucose tolerance test is performed. This technique allows you to identify 98% of women with diabetes mellitus during pregnancy. For 3 days, the pregnant woman must follow a diet with a normal carbohydrate content, the evening before the test she is prohibited from eating, and in the morning the patient takes 100 g of glucose. The glucose content in blood plasma is determined on an empty stomach 1, 2 and 3 hours after a glucose load. Determination of blood hormone levels. When determining the level of prolactin, cortisol, thyroid hormones (T4, T3, TSH, TG, AT-TG), insulin and C-peptide, you should not eat for 5 hours before taking blood from a vein for analysis. As a rule, blood is taken in the morning. For other hormonal indicators, performing the test on an empty stomach and the time it was taken does not matter. Coagulogram. This test must be performed during pregnancy. It shows the blood clotting function and helps prevent the risk of bleeding during childbirth. The analysis is taken in the morning, on an empty stomach. The day before taking blood for testing, you must exclude fatty and sweet foods from your diet. Laboratory tests of urine General examination of urine. For general analysis, it is preferable to use “morning” urine, which is collected in the bladder during the night; this reduces the natural daily fluctuations in urine parameters and thereby more objectively characterizes the parameters under study. A full examination requires at least 70 ml of urine. Urine should be collected after thorough toileting of the external genitalia (failure to comply with this rule may lead to the detection of an increased number of red and white blood cells, which will make it difficult to make a correct diagnosis). You can use a soap solution (followed by washing with boiled water), 0.02 - 0.1% potassium permanganate solution. All urine can be collected for analysis, but it may contain elements of inflammation of the urethra, external genitalia, etc., therefore, as a rule, the first portion of urine is not used. The second (middle!) portion is collected in a clean container, without touching the body with the bottle. The container with urine is tightly closed with a lid. A urine test is performed no later than 2 hours after receiving the material. Urine that is stored longer may be contaminated with foreign bacterial flora. In this case, the pH (acidity) of the urine will shift to higher values ​​due to ammonia released into the urine by bacteria. Microorganisms consume glucose, so with glycosuria you can get negative or underestimated results. Bile pigments are destroyed by daylight. Storing urine leads to the destruction of red blood cells and other cellular elements in it. Quantitative study of sugar content in daily urine. It is necessary to collect daily urine, i.e. all the urine in one day. In this case, the container with urine must be stored in a cool place (optimally in the refrigerator on the bottom shelf at 4-8? C), preventing it from freezing. If there is a large amount of daily urine, only part of it can be brought to the laboratory for analysis. Previously, the patient measures the daily volume of urine as accurately as possible, writes it down in the direction of the doctor, and then, after thoroughly mixing, pours 50-100 ml of the total volume into a clean container, after which he delivers the urine to the laboratory along with the direction. In case of diabetes mellitus, it is also possible to determine sugar in urine collected at fixed (prescribed by a doctor) periods of time. Glucosuric profile studies (determination of sugar levels in urine). To study the glucosuric profile, urine is collected at certain time intervals: I portion - from 9 to 14 o'clock, II - from 14 to 19 o'clock, III - from 19 to 23 o'clock, IV - from 23 to 6 o'clock in the morning, V - from 6 to 6 o'clock in the morning. 9 am. Before analysis, urine samples should be stored in the refrigerator at 4? C. Collection of urine for bacterial examination (“sterility culture”). When collecting urine for bacterial testing (“sterility culture”), the external genitalia should be washed only with boiled water, since the penetration of antiseptic solutions into the urine can give false negative results. For bacteriological examination, urine from the middle portion is collected in a sterile container. Urinalysis according to Nechiporenko. The test is carried out to exclude diseases such as pyelonephritis and glomerulonephritis. The morning portion of urine is examined in the middle of urination (“middle” portion of urine). 15-25 ml is enough for analysis. Storage and delivery to the laboratory are carried out in the same way as for a general laboratory urine test. Urine examination according to Zimnitsky (determining the functional capacity of the kidneys). By performing this test, you can determine the level of filtration and concentration capacity of the kidneys. The Zimnitsky test is performed in 8 separate portions of urine collected during the day. The first contains urine for the period from 6 to 9 o’clock, then urine collection continues at intervals of 3 hours (after 9 o’clock to 12 o’clock - in the second jar, from 12 to 15 o’clock - in the third, etc. In the last, eighth , a jar of urine is collected from 3 to 6 am). Urine collection ends at 6 am the next day. Labels are attached to all containers indicating the number and time interval when a given portion was received (in order not to mix up the jars, it is better to do this in advance, before collecting urine). The containers are kept refrigerated until testing. Even those jars that turn out to be empty should be brought to the laboratory. Laboratory studies of feces Collection of material for scatological examination. For research, freshly excreted feces are collected in an airtight container. When conducting a scatological analysis, no special preparation is required, but if indicated, the doctor prescribes a trial diet, which the patient observes for 4-5 days. Stool should not be sent for research after an enema, administration of suppositories, castor and petroleum jelly, iron supplements (for anemia), bismuth (Vicalin, Vikair, etc.), barium (during X-ray examination), or substances with coloring properties. The stool should not contain foreign impurities, such as urine... A qualitative test for the presence of blood in the stool (“feces for occult blood”). The test is performed if intestinal bleeding is suspected. When conducting an analysis, it is necessary to exclude meat, fish, eggs, all types of green vegetables, and tomatoes from the pregnant woman’s diet for 3-4 days. Identification of protozoa. To identify protozoa (amoeba, lamblia, etc.), freshly excreted, warm feces are examined no later than 15-20 minutes after defecation. Do not store feces in a thermostat or warm water. In extreme cases, when it is impossible to examine stool immediately after receiving it, they are left at a temperature of 3-50? C, but not more than an hour. Feces cannot be examined for the detection of protozoa after oil enemas, barium intake, bismuth salts, etc. Examination of feces for helminth eggs (for worm eggs). Fecal examination for helminth eggs (for worm eggs) is carried out in freshly excreted feces. To do this, 10-15 g of feces are taken from different parts of a single portion into a clean container (see scatological study). In addition, parasites that spontaneously emerge or are isolated during treatment are delivered to the laboratory. Scraping for pinworm eggs. Scraping for pinworm eggs is done in the morning before defecation and urination or in the evening (2-3 hours after the pregnant woman goes to bed). Scraping is carefully carried out from the surface of the folds around the anus and from the lower parts of the rectum using a wooden spatula moistened with a 50% glycerin solution or 1% sodium bicarbonate solution. A spatula with scraping is dipped into a vial with 2-3 drops of 80% glycerin, secured with an elastic band and sent to the laboratory. Scraping (with a match or a wooden spatula soaked in a 50% glycerin solution) can also be done under the nails. Stool analysis for dysbacteriosis (biochemical analysis of intestinal microflora). To collect feces for biochemical analysis of intestinal microflora, it is necessary to take approximately 2 g (1 teaspoon) of feces into a clean jar, tightly close the lid and bring it to the laboratory on the same day, a few hours later. The jar must first be boiled for approximately 20 minutes. Some medical centers provide a special bottle for analysis - you need to take it in advance. The jar intended for microbiological analysis cannot be washed with disinfectants. Stool should not be sent for research after an enema, administration of suppositories, castor and petroleum jelly, iron supplements (for anemia), bismuth (Vicalin, Vikair, etc.), barium (during X-ray examination), or substances with coloring properties. Feces should not contain foreign matter, such as urine. Gynecological tests A cytological examination prescribed by an obstetrician-gynecologist. Examination of gynecological smears “for flora”. A cytological examination is prescribed by a gynecologist. Before visiting a doctor, you should not get too carried away with hygiene procedures; washing with warm water is enough. The day before visiting a doctor, it is better to avoid intimate relationships - this may change the cytological picture. Topical use of ointment preparations and suppositories is undesirable. All of the above is also true when examining hy2-3 smears for flora. The above studies are carried out only according to indications, exclusively as prescribed by a doctor. The frequency of these depends on the stage of pregnancy. If necessary, these studies can be supplemented with other, more accurate methods to confirm the diagnosis, but strictly on the recommendation of the attending physician.

Determining the level of creatinine and performing the Rehberg test is carried out simultaneously in the blood and urine. To determine the level of creatinine, 24-hour urine is used. During the Reyraga sample, when studying in stationary conditions, a pregnant woman should remain in bed, not to take food before the study. In an outpatient basis in the morning, a woman drinks 400-600 ml of water and empties the bladder; Time is fixed. After half an hour, 5-6 ml of blood is taken from a vein to determine creatinine. After another half an hour, after this (an hour after the first urination), urine is collected and its volume is determined. With insufficient diuresis (small amount of urine), urine is collected in 2 hours, and blood is taken an hour after the emptying of the bladder. Gluczotolerant test ("sugar load"). It is carried out only if there are preliminary results of determining glucose on an empty stomach, without load. One-hour test for glucose tolerance is recommended to be carried out by all pregnant women for a period of 24-28 weeks. The need for screening at an earlier period (16-20 weeks) can occur in those pregnant women whose closest relatives suffered from diabetes mellitus, as well as in patients with persistent glucosuria (the presence of sugar in the urine), obesity and in the presence of gestational sugar during the previous pregnancy diabetes, macroSomium (large fetus) or inexplicable intrauterine death of the fetus. When conducting one -hour test, there is no need to exclude food on the eve, however, after the oral administration of 50 g of glucose, a woman should not eat within an hour, up to the fence of venous blood. With a glucose concentration of 7.7 mmol/l or more, the test is considered positive; In this case, a standard (3-hour) oral glucosotolerant test is carried out. This technique allows you to identify 98% of women with diabetes of pregnant women. Within 3 days, the pregnant woman should follow a diet with the usual carbohydrate content, in the evening on the eve of the study, they are prohibited, and in the morning the patient takes 100 g of glucose. The content of glucose in the blood plasma determines the onnachics 1.2 and 3 hours after the load of glucose. Determining the level of blood hormones. When determining the level of prolactin, cortisol, thyroid hormones (T4, TZ, TTG, TG, AT-TG), insulin and C-peptide, you can’t eat for 5 hours before taking blood from the vein for analysis, as a rule, blood is taken in the morning. For other indicators of the hormonal background, the analysis of on an empty stomach and the time of its delivery does not matter. Coagulogram. This analysis must be carried out during pregnancy. It shows a coagulant function of blood, helps prevent the risk of bleeding in childbirth. The analysis is taken in the morning, on an empty stomach. The day before taking blood for examination from the diet, it is necessary to exclude fat and sweet. Laboratory studies of urine General study of urine. For a general analysis, it is preferable to use “morning” urine, which is collected in the bladder during the night; This reduces the natural daily vibrations of urine indicators and thereby more objectively characterizes the studied parameters.

You can use a soap solution (followed by washing with boiled water), 0.02 - 0.1% solution of potassium permanganate. For analysis, you can collect all the urine, however, elements of inflammation of the urethra, external genital organs, etc., can be obtained into it, therefore, as a rule, the first portion of urine is not used. The second (medium!) Portion is collected in clean dishes, without touching the body in the body. The container with urine is tightly closed with a lid. Urine is analyzed no later than 2 hours after receiving the material. Urine, which is stored longer, can be polluted by an extraneous bacterial flora. In this case, the pH (acidity) of urine will move to higher values ​​due to ammonia released into urine by bacteria. Microorganisms consume glucose, therefore, with glucoseuria, you can get negative or lowered results. The gall pigments are destroyed in daylight. Storage of urine leads to the destruction of red blood cells and other cellular elements in it. Quantitative study of sugar in daily urine. It is necessary to collect daily urine, i.e., all urine in one day. At the same time, the capacity of the urine must be preserved in a cool place (optimally-in the refrigerator on the lower shelf at 4-8? C), preventing it from freezing. With a large amount of daily urine, only part of it can be brought to the laboratory for analysis. Previously, the patient measures the daily urine, writes it in the direction of the doctor, and then, having thoroughly mixes, casts 50-100 ml from the total volume into a clean container, after which he delivers urine to the laboratory along with the direction.

Before the analysis, a portion of urine should be stored in the refrigerator at 4? S. Collection of urine for bacterial examination ("sowing for sterility"). When collecting urine for bacterial examination (“sowing for sterility”), the external genitalia should be washed only with boiled water, because the ingress of antiseptic solutions in the urine can give false negative results. For bacteriological examination, urine from the middle portion is collected in sterile dishes. The study of urine according to Nechiporenko. The sample is carried out to exclude diseases such as pyelonephritis and glomerulonephritis. The morning portion of urine in the middle of urination ("average" urine) is examined. For analysis, 15-25 ml is enough. Storage and delivery to the laboratory are carried out in the same way as with a general laboratory study of urine.

Urine collection is finished at 6 am the next day. Labels are glued to all containers indicating the number and time interval when this portion was received (so as not to confuse banks, it is better to do this first, before the start of urine collection). The containers before the study are stored in the cold. You need to bring even those banks that turned out to be empty to the laboratory. Laboratory studies of feces collection of material for coprological research. For research, freshly fed feces are collected in a leaky container. When conducting a coprological analysis of special training, it is not required, but when testimony, the doctor prescribes a trial diet, which the patient observes 4-5 days. The research cannot be directed after the enema, the introduction of candles, the use of castor and petroleum jelly, iron preparations (with anemia), bismuth (Vikalin, Vicahir, etc.), barium (with an X -ray examination), substances with coloring properties. The feces should not contain extraneous impurities, such as urine ... A high -quality test for the presence of blood in feces (“feces for hidden blood”). The sample is carried out if intestinal bleeding is suspected. During the analysis, it is necessary to exclude meat, fish, eggs, all types of green vegetables, tomatoes from the food diet for 3-4 days. Identification of the protozoa. To identify the protozoa (amoeba, giardia, etc.), freshly, warm feces are examined no later than 15-20 minutes after defecation. You can not keep feces in a thermostat or warm water. In extreme cases, when it is impossible to examine the bowel movements immediately after receipt, they are left at a temperature of 3-50? C, but not more than an hour. The feces for the detection of the protozoa can not be examined after oil enemas, the intake of barium, the salts of the bismuth, etc. Exploring the feces on helminth eggs (on worm eggs). The study of feces for helminth eggs (on worm eggs) is carried out in freshly -fed feces. To do this, 10-15 g of feces are selected from different sections of a single portion into a clean container (see Copolochean research). In addition, the laboratory is delivered spontaneously that spontaneously released or distinguished during the treatment of parasites. Scraping to the eggs of pinworms. Scraping to the eggs of pinworms is done in the morning before defecation and urination or in the evening (2-3 hours after the pregnant woman went to bed). Squinting is carefully made from the surface of the folds in the circumference of the anus and from the lower parts of the rectum by means of a wooden spatula moistened with a 50 % solution of glycerin or 1 % solution of two -hewole sodium. A spatula with a scraping is lowered into a bubble with 2-3 drops of 80% glycerin, strengthened with an elastic band and sent to the laboratory. Scrapings (a match or wooden spatula moistened in a 50% glycerol solution) can be carried out under the nails. Analysis of feces for dysbiosis (biochemical analysis of intestinal microflora). To collect feces for a biochemical analysis of the intestinal microflora, it is necessary to select approximately 2 g (1 teaspoon) of bowel movements in a clean jar, close the lid tightly and bring on the same day, a few hours later to the laboratory.

How to properly prepare for a biochemical blood test?

Using a biochemical blood test (it is taken from a vein), you can find out the blood levels of glucose, total protein, cholesterol, urea, creatinine, bilirubin and other components, including some hormones. Expectant mothers donate blood for biochemistry 2 times: upon registration and at the 30th week.

Here the requirements are stricter than when passing the UAC. You should not eat anything 12 hours before the test. That is, late dinner is cancelled. A night trip to the refrigerator too. Dinner should be light, without fried, spicy, or sweet foods. If, among other indicators, it is necessary to find out the level of cholesterol, then you need to exclude any fatty foods, even those containing so-called hidden fats: sour cream, butter, cheese, cottage cheese, sausage. You can drink water before the test, but as little as possible, only if you really want to. Drinking may affect the concentration of components in the blood, which will distort the test results.

If the test components contain hormones, you should not enter the laboratory assistant’s office in an agitated state. It’s better to sit in the hallway for half an hour to calm down and get your hormonal levels in order.

Preparing for the second screening during pregnancy

It’s easy to prepare for 2nd trimester screening:

• You must follow a diet for 1 day, but now the requirements are no longer so strict. If you really want a certain product, don’t cruelly deny yourself. In general, the recommendations are similar to those in preparation for 1st screening: Avoid fatty foods
• Avoid allergens
• Don't eat chocolate, citrus fruits, seafood

General rules for taking a blood test

And a few more things that are not obvious at first glance that may affect the result of the analysis.

• It is not recommended to chew chewing gum before the test.
• If you are taking any medications, such as diuretics, you should talk to your doctor about whether you should skip a pill the night before your test.
• It is not recommended to take tests after physical activity. For example, if you do pregnancy exercises in the morning, it is better to donate blood before training.
• After other physical activity - for example, if you ran after a minibus or climbed the stairs - you need to sit for 15-20 minutes, and only then go into the laboratory office.
• You should not smoke less than 1 hour before donating blood.
• It is not advisable to take a blood test immediately after physiotherapy, x-rays, ultrasound, or a massage session.

Preparing for your first pregnancy screening

To properly prepare for the first screening during pregnancy and get the most accurate results, follow these simple recommendations:

• The day before the examination, follow a special diet - this is necessary for an accurate blood test: Avoid fatty foods
• Avoid allergenic foods
