Why should pregnant mothers during pregnancy blood test

Why should pregnant mothers during pregnancy blood test? Some mothers can not understand, we often forget check the blood type. Experts tell us that pregnant mothers to check the blood type is the following: to avoid pregnant mother's blood type and mother of children fetal blood group incompatibility, leading to the possibility of fetal or neonatal hemolysis.

Q: What makes the ABO blood group incompatibility, what harm had made

A: During pregnancy, maternal child blood group incompatibility can cause hemolytic disease of newborns. ABO blood group incompatibility occurred in the O-pregnant women, husbands blood type is A, B type, AB type of situation. These antibodies via the placenta into the fetal circulation, damage to fetal red blood cells, causing hemolysis, higher antibody titers greater harm. Hesitate to ABO blood group antigens are widely distributed in nature, in the body after exposure of pregnant women have to produce antibodies, ABO hemolytic disease incidence in any one child. Usually less severe, the general treatment can, most do not require exchange transfusion therapy.

Q: Rh blood group incompatibility over how to do hair

A: In order to prevent any eventuality, in early pregnancy, mid and late check maternal blood antibody titers. High antibody titer value, to monitor the fetal condition.

In recent years, where the Rh (-) Mother, Rh () father, in the abortion or within 72 hours after delivery will receive anti-D gamma globulin to prevent blood Rh factor on the production of anti-D antibody, thereby ensuring the future child, the baby's safety . In addition, enter the Rh positive blood should be avoided.

Event of the above, has little effect on pregnant women, but great harm to the fetus or the newborn: pregnancy can cause miscarriage, premature delivery, intrauterine growth retardation, fetal distress, fetal death, stillbirth, etc.; such newborns can be due to severe anemia, heart failure and death, but also because of massive invasion of brain cells caused by bilirubin kernicterus. Kernicterus high mortality rate, even if survived, will also affect the development of nerve cells of sick children and athletic ability. Therefore, early prevention is very important.
