Mother who is rh negative

Your blood type depends on the genes you inherit from your parents. Whether you're RhD positive or negative depends on how many copies of the RhD antigen you've inherited. You can inherit one copy of the RhD antigen from your mother or father, a copy from both of them, or none at all. You'll only have RhD negative blood if you don't inherit any copies of the RhD antigen from your parents.

If the father has two copies of the RhD antigen, every baby will have RhD positive blood. An RhD positive baby will only have rhesus disease if their RhD negative mother has been sensitised to RhD positive blood.

A woman also might get a dose of Rh immune-globulin if she has a miscarriage, an amniocentesis , or any bleeding during pregnancy. If a doctor finds that a woman has already developed Rh antibodies, her pregnancy will be closely watched to make sure that those levels are not too high.

In rare cases, if the incompatibility is severe and a baby is in danger, the baby can get special blood transfusions called exchange transfusions either before birth intrauterine fetal transfusions or after delivery.

Exchange transfusions replace the baby's blood with blood with Rh-negative blood cells. This stabilizes the level of red blood cells and minimizes damage from Rh antibodies already in the baby's bloodstream.

Thanks to the success rate of Rh immune-globulin shots, exchange transfusions in Rh-incompatible pregnancies are rarely needed in the United States. If you're not sure what your Rh factor is and think you're pregnant, it's important to start regular prenatal care as soon as possible — including blood-type testing.

With early detection and treatment of Rh incompatibility, you can focus on more important things — like welcoming a new, healthy baby. Reviewed by: Armando Fuentes, MD.
