Human Blood Groups

Human blood groups refer to the classification of blood based on the presence or absence of specific antigens on the surface of red blood cells, primarily categorized into the ABO system (A, B, AB, and O). The Rh factor is a separate antigen that can be present (Rh-positive) or absent (Rh-negative) on the surface of red blood cells, influencing blood compatibility in transfusions and pregnancy.
