The ABO blood group system classifies blood types according to the different types of antigens in the red blood cells and antibodies in the plasma. They use the ABO system alongside the RhD antigen status to determine which blood type or types will match for a safe red blood cell transfusion.

Before the ABO blood system was discovered, doctors often wondered why some patients died after a blood transfusion while other patients didn't. This left scientists baffled as to what was happening. Looking back now, the patients who died probably had incompatible donors.

As well as the ABO blood group systems, 29 other blood group systems have been identified. These blood groups have names such as Rh, MNSs, Lutheran, Kell, Kidd, and Lewis. The chemical structures of the A, B and H antigens are very similar.
