Karl Landsteiner discovered the ABO blood group system in 1901 which classified blood into A, B, AB and O groups and allowed for safe blood transfusions. The ABO and Rh blood grouping systems are based on detecting agglutination reactions between antigens on red blood cells and antibodies in plasma through a protocol using agglutination to identify a person's blood group which is important for blood transfusions.

9. PRINCIPLE
•The ABO and Rh blood grouping is based on
agglutination reaction.
•In the abo blood grouping system,
agglutination reaction takes place
Between the surface proteins that are
found on the red blood cells and the antibodies
against them.
