Rh isoimmunization

Rh disease (also known as rhesus isoimmunization, Rh (D) disease) is a type of hemolytic disease of the fetus and newborn (HDFN). HDFN due to anti-D antibodies is the proper and currently used name for this disease as the Rh blood group system actually has more than 50 antigens and not only D-antigen. [Source: Wikipedia ]
