How does Rhogam prevent erythroblastosis fetalis (HDN, hemolytic disease of the newborn)?
If a mother who is Rh negative carries a fetus who is Rh positive, she will make antibodies against its Rh positive RBCs after being exposed to the infant's blood during labor and delivery. By giving a dose of anti-Rh antibody (Rhogam) just before or after delivery, the fetal red cells will be agglutinated and removed from the mother's circulation before her immune system will have time to make anti-Rh antibodies that would endanger her next Rh-positive offspring.
