One of the characteristics of blood groups is their hereditary nature. Blood groups are determined by the presence or absence of specific antigens on red blood cell membranes. There are two types of blood groups: 1. ABO 2. Rh Both types of antigens are located on the surface of red blood cells. ABO blood group antigens still hold great importance in blood transfusion medicine. They are the most immunogenic antigens of blood groups. The most common cause of death resulting from blood transfusion is administrative error, where an incompatible blood type is injected. ABO blood group antigens also appear to have been important throughout our evolution, as the prevalence of different ABO blood groups varies among different populations, indicating a selective advantage for a particular blood group.
