Question

Quizplus · Accepted Answer

Erythroblastosis fetalis, also known as hemolytic disease of the newborn, is an alloimmune disease. This occurs due to incompatibility of antigens between maternal and fetal blood, which leads to maternal antibodies attacking fetal red blood cells. This can cause fetal anemia, jaundice, organ damage, and even death. It is most commonly caused by Rh incompatibility between mother and fetus.
