The discovery
of human blood groups was made in 1901 by the famous Austrian scientist
Dr. Karl Landsteiner. He who won the Nobel Prize for his discovery.
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.
