A young couple who decide to conceive a child should know how important blood compatibility is for this purpose. When planning the birth of a child, parents must take into account their blood types in order to avoid complications.

During the process of fetus formation, maternal and paternal blood is mixed. In such a way the blood of the child if formed. The baby can have any blood type. Since the embryo is formed, there are four groups simultaneously, but the percentage ratio is different. The highest percentage has the blood of the parents. Therefore, the child will have blood type either of father or mother.

When the parents have the identical blood type, in most cases (95-98 %) the child's type will be the same. If the parents’ groups are different, then the baby has 25% to inherit one of them. Thus, the child can have I, II, and III and IV group of blood.

It is believed that the child will be healthier if dad's blood group is higher than mother’s (for example, if you (a future mom) have the I group of blood, and the husband another, in any case, it will be higher than yours). Whatever it is, with the same blood group parents will have a safe pregnancy.

According to gynecologists, blood group for prospective parents is beside the point. However, Rh factor plays more important role, it is desirable to have the same Rh factor. So, in order to avoid problems in conceiving and carrying a child, it is important that both partners have the same Rh factor.

Rh factor is a special protein that is on the surface of red blood cells: if a protein is available, then Rh factor is positive, if it is not, then Rh factor is negative.

If the Rh factor of blood from the woman’s side is negative, then, ideally, negative it should be to a man. In the case, if a woman has positive Rh, then for the benefit of the unborn child it is advisable to the man to have positive as well.

In erythrocytes of human blood, according to the above system, there are antigens A and/or B, or absent (0). And in the blood plasma there can be antibodies to antigens A and B.

According to system "A-B-zero", there are four main blood groups:

  • Group I (0) in the plasma there are agglutinins A and B, in erythrocytes there are no agglutinogens.
  • Group II (A) – the plasma contains agglutinins B, and in erythrocytes – A.
  • Group III (B) – the plasma contains agglutinins A, and in erythrocytes – B.
  • Group IV (AB) in the plasma agglutinins are absent, and in erythrocytes agglutinins A and B are present.
