He divided the blood group into four categories being A, B, AB, O . His discovery made him understand that two distinct chemical molecules called antigens and antibodies were present on the surface of the red blood cells. He found that if these categories were not matched properly it could cause clumping or agglutination in the arteries and veins of the recipient and lead to a bad reaction that could sometimes even result in loss of life.

To learn more about human blood types scientist have worked with Rhesus monkeys as there are many similarities between the two species. While studying them it was found that these monkeys had a certain protein called the Rh protein. Some people possess this protein and are called Rh +ve. If they do not have the protein they are Rh – ve. When describing the Blood type the Rh +ve or -ve is written as O+ve or AB+ve or O-ve or AB-ve. The Rh type is especially important in Pregnancy.
