Rh treatments are ineffective once a woman has developed antibodies. RhIg may also be given after amneocentesis or postpartum sterilization. Rh-negative women should also receive treatment after any ectopic pregnancy, miscarriage, or induced abortion to prevent any attacks on a future fetus. The treatment is only valid for the pregnancy for which it is given. No treatment is needed for an Rh negative father. If the child is Rh-positive, she should be given another dose of RhIg shortly after birth to prevent sensitization to cells left over by the fetus. If an Rh-negative woman has not yet been sensitized, she may be given RhIg around the 28th week of pregnancy to prevent sensitization. The only known side effects are soreness at the injection site and slight fever, which both go away.

It can be injected into the arm or buttocks, and is safe for pregnant women to use. A medication called Rh immunoglobulin (RhIg) can help prevent sensitization by keeping her cells from being able to respond to the Rh factor. Hemolytic disease in the child can be prevented if the mother has not yet developed antibodies. Another test called an antibody screen can be used to determine whether or not sensitization has occurred. HOW CAN RH FACTOR PROBLEMS BE PREVENTED?Ī simple blood test can determine if a woman is Rh positive or negative. Sensitization can also occur if a mother has had a miscarriage, an induced abortion, an ectopic pregnancy, or a blood transfusion. If she becomes pregnant with another Rh-positive fetus, there will be more antibodies that could cause even more serious damage. This condition is called hemolytic disease, and can be serious enough to cause illness, brain damage, or even death.Įven after the Rh-positive child is born, the antibodies do not go away. They then become sensitized, causing antibodies to be formed that will fight and break down the fetal blood cells, producing anemia. This can cause a small number of Rh-negative women to react to the fetal blood as if they are allergic to it. Although the mother and fetus do not share blood systems, the fetal blood can go through the placenta into the mother’s system. While carrying this child, the woman may become sensitized. If an Rh-negative woman has a child with an Rh-positive man, their child can be Rh-positive. If this occurs, the negative person will become sensitized, meaning that he or she produces antibodies to fight the Rh factor. The Rh factor causes problems when a person with Rh-negative blood comes in contact with someone with Rh positive blood. However, it can potentially affect a pregnancy. Whether or not you are positive does not affect your overall health. Those that do not are considered Rh negative. Most people have the Rh factor, meaning that they are Rh positive. There is also an Rh factor, which is the type of protein in red blood cells. There are several different blood types, such as A type, B type, and O type. This page will give you basic information on the Rh factor and what it can mean for your pregnancy. This can be problematic if the mother does not have the Rh factor but the fetus’s blood does. More than 85% of people in the world are Rh positive, meaning that they have the Rh antigen. During pregnancy, it is important to have a blood test to find out your blood type.
