When a mother is Rh negative and her fetus is Rh positive, there is a risk that the baby's Rh positive red blood cells will enter the mother's bloodstream during pregnancy and delivery, causing the mother's immune system to produce antibodies against the Rh factor. These antibodies can cross the placenta and attack the baby's red blood cells, leading to hemolytic disease of the newborn (HDN) in a second pregnancy.
