Blood Types - TSV
Blood types are biological characteristics classified by the types of antigens present on the surface of red blood cells. Eight main blood types are defined by the combination of the ABO blood group system (Type A, B, O, and AB) and the Rh factor (positive or negative). The ABO blood group system, discovered by Karl Landsteiner in 1901, forms the foundation of transfusion medicine and is an essential classification system for preventing the dangers of incompatible blood transfusions. The Rh factor, discovered in 1937, plays a particularly important role in preventing hemolytic disease of the newborn caused by maternal-fetal Rh incompatibility during pregnancy.
