Since Rh immune globulin won’t be helpful, the best treatment is close monitoring for the remainder of your pregnancy. There’s a small chance your provider will want to deliver early, but this depends on how severe the fetus’s Rh disease is. Complications don’t usually happen during a woman’s first pregnancy. This is because it’s unlikely that your blood will mix with the fetus’s blood until delivery, which means antibodies won’t form until after the fetus is born.

In a full-term baby who is less than 24 hours old, the levels of bilirubin should be less than 6.0 milligrams per deciliter. A positive indirect Coombs test is a sign of Rh incompatibility. This test uses a blood sample to look for the presence of cell-destroying antibodies within the plasma of your blood. Bilirubin is a chemical that’s created from the breakdown of red blood cells. Too much bilirubin is a sign that the liver, which is responsible for processing old blood cells, is having trouble. People may consider undergoing an Rh screening test if they plan to become pregnant, require a blood transfusion, or donate blood.

Treatment of erythroblastosis fetalis usually entails one or more exchange transfusions. The disease can be avoided by vaccinating the mother with Rh immunoglobulin after delivery of her firstborn if there is Rh-incompatibility. The Rh vaccine destroys any fetal blood cells before the mother’s immune system can develop antibodies. 1 Rh incompatibility can also occur when a Rh-negative individual of childbearing age receives a Rh-positive blood transfusion. Interestingly, the presence of ABO incompatibility can have a protective effect against the development of Rh alloimmunization. ABO incompatibility occurs when a pregnant individual with type O blood carries a fetus with blood type A, B, or AB. This early destruction reduces the likelihood that maternal antigen-presenting cells will process Rh(D) antigen, thereby lowering the rate of Rh sensitization. Rh incompatibility occurs when a woman who’s Rh-negative becomes pregnant with a fetus with Rh-positive blood.

Another blood test, called an antibody screen, can show if an Rh-negative woman has already developed antibodies to Rh-positive blood. Any woman who is Rh-negative and is having a child with someone who is Rh-positive or with an unknown Rh status is at risk for Rh incompatibility.

Rh Factor: What is it and Why Does it Matter?
Rh factor incompatibility only becomes an issue during pregnancy when you’re Rh-negative and the fetus is Rh-positive. Your provider treats Rh incompatibility with an injection of Rh immunoglobulin (RhIg). Try not to worry — your provider will keep a close eye on you and get you the treatment you need to prevent any complications. If your body already has Rh antibodies, the fetus is at risk for Rh disease.
