Blood type can tell you a lot about a person. As a rule, it determines his character. The blood type remains unchanged throughout life, performing its main function, which is to support the vital functions of the human body.
Thus, a man and a woman must have perfect compatibility before planning a child. Blood type 4 positive is considered the rarest. It consists of AB antigens. Among the people it is also called mixed.
Rh factor and more
The most common is the Rh factor with a plus sign. It occurs in 85% of cases. When future parents are about to start conceiving, it is necessary that their Rh factors are compatible. Otherwise, various complications are possible that are associated with pregnancy, as well as the health of the baby.
If both parents have the same blood type, but one of them has a negative Rh factor, fetal rejection may occur. In addition, miscarriages are possible, as well as failures when trying to conceive.
The Rh factor has an important characteristic. This is variability. This is precisely the reason that during the period of bearing a child, the Rh factor can change in some women.
At the moment, the fourth blood group has not been sufficiently studied. It is especially difficult to predict how the body will behave during pregnancy. So compatibility sometimes fixes itself. In this way, a woman’s body is, as it were, rebuilt to make it possible to conceive.
Compatibility of the fourth blood group is universal. So, any donor is suitable for these people. If we talk about the owner himself, he is rarely suitable for this role. This is possible if the recipient has the same blood group with any Rh factor.
History of appearance
To date, there are three main hypotheses about the origin of the blood of the fourth group.
They are as follows:
- mixing of races;
- food exposure;
- counteraction to viruses.
The first hypothesis suggests that the fourth blood group arose as a result of mixing of races. Due to the fact that previously such marriages were quite rare, the compatibility of AB antigens was not determined. It should be noted that such people make up only 5% of the total population of the planet.
As you know, today there is an increased consumption of synthetic products. All of them are often subjected to active temperature treatment. Also, products that are created artificially have entered the people’s diet and become firmly established. When their elements enter the blood, its composition can change.
Interestingly, the fourth group of positive Rh factor can often be determined in people living in Japan, Australia and Southeast Asia. Thus, the presented hypothesis is possible, although unlikely.
The latest version of the appearance involves the impact of infections of viral origin on the human body. As is known, until 1500 such diseases were not discovered. Viral infections of measles, influenza and other ailments appeared a little over five hundred years ago. As a result, the immune system changed the constituent elements of the protein contained in the blood, which happened because the body independently began to find ways to fight infections. Thus, compatibility of AB antigens appeared.
Donation procedure
For the convenience of the donor, the procedure itself takes place in the donor chair. Using sterile instruments, 400 to 500 grams of blood are taken from the donor over 15 minutes, starting from 50 drops per minute. Part of the blood is sent for tests for infections, group and Rh factor. Plasma donation lasts about 30 minutes, platelets - 1.5 hours.
Immediately after blood sampling, you should not engage in physical labor, drive vehicles, or drink alcohol.
Some facts
Representatives of the fourth blood group in question are distinguished by their endurance. They can easily adapt to completely new climate and living conditions. In addition, such people calmly tolerate changes in diet. Therefore, the diet is not scary for them.
Resistance to all kinds of diseases is also observed. As for the digestive system, it is sensitive in owners of blood group 4. Therefore, most people require a diet. Another well-known fact is that Jesus Christ had the fourth blood type. True, there is no exact confirmation of this.
The characteristics of people of this blood group are as follows. They are calm, tactful, balanced and friendly. In addition, such a person has sociability, he will easily get along with other people. Sadness and depression visit him quite rarely.
Despite the external positivity and balance, the inner world of these people is full of worries. They are often afraid of making mistakes and making the wrong decision. Sometimes it is quite difficult for them to decide something. In order to suppress anxiety within oneself, active mental activity is used, various physical activities are performed that can take away a large amount of energy. People with blood type 4 are subject to mysticism. Thus, they are often able to foresee various events.
The fourth blood group, as a rule, belongs to creative people.
The following plays a big role in their lives:
- emotionality;
- fantasy;
- perfect taste;
- sincerity;
- love for everything beautiful;
- developed intuition.
Due to their sophisticated perception of reality, such people are capable of going to extremes. Under the influence of intense emotions, they sometimes fail to gain control over themselves. A person who has compatibility of A and B antigens often creates idols for themselves. They are characterized by absent-mindedness, impracticality, they are not always ready to solve problems that arise, and are sensitive to insults.
Is donation safe?
Yes. Blood donation is absolutely safe. Sterile instruments are used to draw blood; the feeling of weakness and dizziness during and after the procedure quickly disappears.
However, there are relative and absolute contraindications for blood donation.
Absolute contraindications for blood donation
Absolute contraindications for blood donation are diseases such as:
- HIV AIDS,
- Viral hepatitis
- Tuberculosis
- Syphilis
- Infectious diseases
- Malignant tumors
- Central nervous system diseases
- Mental illness
Relative contraindications are temporary contraindications; these include some diseases and conditions in which donation is temporarily contraindicated. Relative contraindications are:
- Operations, minor surgical interventions (tooth extraction)
- Pregnancy, lactation
- ARVI, sore throat
- Menstruation
- Allergies in the acute stage
- And etc.
Special recommendations for choosing nutrition
People who have the fourth blood group, whether positive or negative Rh factor, who are overweight, must follow a certain diet. Thus, a special diet is provided to adjust their body weight.
Some foods that are contraindicated for other blood types may be ideal for the fourth and vice versa. However, given the tendency of the digestive system to disorders, people with blood group 4 need to be more picky about food. If you have any problems with the digestive system, it is advisable to visit your doctor. They will be prescribed a special diet that is most suitable for the characteristics of a particular blood type.
When choosing your diet, it is recommended to study some guidelines. In this case, a diet that includes the consumption of lean meat is preferable. These are turkey, rabbit and other varieties. You can eat vegetables with low starch content. The diet for representatives with the fourth blood group should include fermented milk products. It is desirable that they have low fat content. It is recommended to add olive oil to food. It is worth giving up marinades, spicy and overly salty dishes. As for fruits, they will be beneficial. True, it is advisable not to experiment with exotic species. If people who have AB antigen compatibility are prescribed a diet, they will have to give up sunflower seeds, buckwheat and peanuts. There are no special prohibitions on drinks. The main thing is to have everything in moderation.
As you can see, the diet, which is designed for people with blood type IV, is not particularly strict, although it has its own characteristics. You will need to limit yourself in consuming high-calorie foods. At the same time, you don’t have to give up your usual diet, just change it a little. It is not recommended to eat dishes made from wheat, as it can prevent excess weight loss.
Advantages and disadvantages
The main advantages include:
- is the youngest blood group;
- compatibility of the advantages of A and B antigens;
- flexibility of the immune system.
Disadvantages include:
- high sensitivity of the digestive system (sometimes a special diet is required);
- compatibility of deficiencies of A and B antigens;
- low resistance to viral infections.
People with blood type IV, positive or negative Rh factor, are prone to cancer, heart disease, and anemia.
Where to donate blood
So, to become a blood donor, you need to go to a blood transfusion station in your city.
According to the law “On the Donation of Blood and Its Components,” since 2013, private medical organizations have not been able to take blood, nor even procure, store, or transport it. This law was passed in order to tighten blood testing, storage and transfusion, thereby protecting recipients from possible infection and complications associated with blood transfusion.
In order to donate blood, let’s say in Moscow, just enter “Where can I donate blood in Moscow?” into the search engine to display a list of blood transfusion stations in the city of Moscow.
Using the list, you can choose a blood transfusion station that is closer to you in geographical location. Using this example, you can easily find a list of blood transfusion stations in your city.
Key Strategies
People who have compatibility of A and B antigens in their blood should adhere to the following recommendations:
- express social activity, try to avoid situations of intense competition;
- create a plan of tasks that need to be solved over a certain period of time and strictly follow it;

Thus, it is not so important what kind of blood a person has. The main thing is what are the goals set for him. It is also important to determine for yourself ways to achieve them. The information presented gives only a general idea about people with the fourth blood group. The rest depends on the person himself, his character, characteristics and willpower.
