If you at least once in your life donated blood as a donor, you probably learned about yourself some interesting new information related to the individual characteristics of your body. How to understand if your blood phenotype is rare? And what is this strange characteristic feature of the organism?
The study of this feature is necessary first of all in order to understand the compatibility of the blood of the donor and the patient, who expects to receive it. If the phenotypes do not match, transfusion can lead to serious complications, even to the death of the patient. Thus, a patient with 2 negative blood groups cannot be transfused with the same group, but with the presence of a positive Rh factor. Looking ahead, I would like to add that the Latin letter D is responsible for the Rh factor, if the phenotype has a patient that is considered Rh-positive and vice versa.
Compatibility testing of blood is carried out primarily by the coincidence of antigens with different impact forces, also called immunogenicity.
Antigens A and B
One of the key factors influencing the definition of blood phenotype is the presence of antigens, denoted by Latin letters A and B. In the absence of both types of erythrocytes, the blood group is considered I, if there are only A – II, if there is only B – III. If the structure contains red blood cells A and B – this is the IV group. Based on the above designations, it can be concluded that any blood group I can be transfused to any person, but its owner is allowed only to be transfused I. People who do not have antigens A and B are considered owners of a rare blood phenotype. If red blood cells get inside, to which the organism has no stability, then this can lead to irreversible processes. They certainly will not entail the recovery of the patient.
Rare blood type phenotype
According to statistics, the frequency of occurrence as a percentage of the total population of the planet is:
As you can see, the rarest blood group is VI. Turning away from the main topic, I would like to draw attention to the fact that there is a theory of dependence of a person’s character and interests on his blood group. This kind of research was carried out by Japanese scientists, who were convinced of the truth of their guesses. It turned out that the blood group is not only a characteristic hereditary trait, but also has the strongest development on the personality itself, its views and beliefs. In addition, knowing such a feature of the body, you can be sure which products your body will absorb much better than others.
According to this version, the owners of the first blood group are endowed with strong health, are less susceptible to mental illness, and are also considered to be the owners of a strong will and spirit. It is recommended to eat poultry and beef.
Owners of the second blood group are diligent and hardworking, they are used to bring their affairs to the end. They have friendliness and easily converge with people, and also have an innate level of empathy. Such people love pork and tolerate it well.
Those who were born with the third blood group, as a rule, easily adapt to new life situations and are also prone to perfectionism. They love to do what they want themselves, and quite freedom-loving. Lamb is best for them.
Holders of the fourth blood group tend between the mind and feelings to be guided by the second. They are often leaders in any company and it is easy for them to convince others in their point of view. Any food is suitable for such people, they tolerate almost any innovations in the diet.
Rare Rh Factor
The next aspect affecting the compatibility of human blood is the determination of the Rh factor. These antigens include: D, d, C, C, E, e. They form pairs among themselves, such as DD, dd, CC, ss, EE, her, Dd, Cc, Her. According to statistics, the most frequent Rhesus antigens on the entire planet occur at such intervals:
Thus, the rare blood phenotypes of the Rh factor include ccDEE, CCDEe, CcDEE. The most common phenotypes are: CcDEe, CcDee, ccDEe, CCDee, ccddee.
Hopefully, this article has helped you answer the question of how rare the blood is. I want to believe, the information you read motivates donation and help other people!
