If the mother is Rh-negative, her immune system treats Rh-positive fetal cells as if they were a foreign substance. The mother’s body makes antibodies against the fetal blood cells. These antibodies may cross back through the placenta into the developing baby. They destroy the baby’s circulating red blood cells.

Rh factor incompatibility does not cause signs and symptoms in the pregnant woman. The baby, however, can develop hemolytic anemia, a condition in which red blood cells are destroyed. Red blood cells contain hemoglobin, a substance that carries oxygen, so the lack of red blood cells leads to a lack of oxygen in the body.

How are Rh positive and negative blood types classified?

There are four blood types — A, B, AB, and O. Each of the four blood types is further classified based on the presence of another protein on the surface of RBCs that indicates the Rh factor. If you carry this protein, you are Rh positive. If you don’t carry the protein, you are Rh negative.
