RH analysis
RH is an analysis required by a gynecologist for pregnant women, especially pregnant women, for the first time. It is done by taking a blood sample from the pregnant woman. For example, if the blood type of the woman (B +) is evidence that her blood type B, The fetus takes the dominant qualities in the father and takes the antigen and God loves it from the father; where the fetus remains in the womb of his mother until birth and then the problem is here At birth, so that the uterus is open and blood vessels are exposed; The mother has to pick up anything from the fetus. When the doctor cuts off the umbilical cord, some blood may fall from the fetus and mingle with the mother’s blood. The mother will acquire the antigen from the baby. The mother feels that something unusual has entered her body. This takes 72 hours. Here, women should be given a needle immediately after birth.
The needle is an anti-Rh; the mother is given antibodies from the outside to fight the antigen before feeling it and the body to sort out the antibodies. By doing this, the antigen is eliminated in the mother’s body and does not harm her, but the danger is on the second baby. If the mother does not give the needle and intends to conceive with another child, the fetus will acquire the antigen from his father, but this fetus will find antibodies that fight the antigen, which may result in a liver link in the fetus because the liver tries to get rid of the antigen but can not complete it as it does in adults , And the child may be born infected With mental retardation God forbid, hence the importance of conducting this analysis after the first pregnancy and during pregnancy.
Although the first pregnancy may be safer, it is safer to have a specific test to detect antibody levels in the blood. In order to overcome this (incompatibility in RH), the pregnant woman is given a syringe in the 28th week of pregnancy if the test is negative, and the injection is immediately after birth.
