The Rh factor test is done during pregnancy to identify a woman's Rh factor. In some cases, the baby's father might need an Rh factor test, too. During pregnancy, problems can occur if you're Rh negative and the baby you're carrying is Rh positive. Usually, your blood does not mix with your baby's blood during pregnancy.
If an Rh-negative pregnant woman is carrying an Rh-positive fetus, the fetus may be at risk of hemolytic disease of the newborn, in which antibodies made by the mother against the Rh antigen may cross the placenta and destroy the fetus's red blood cells. RhoGAM administered to pregnant Rh- women may prevent this disease.
