The Blood Type Discovery Quiz – The Discovery of Blood Groups

For centuries, doctors tried transfusing blood with dangerous and often deadly results. In 1901 Karl Landsteiner discovered that human blood falls into groups, now called A, B, AB and O, explaining why some transfusions failed.

Later discoveries added the Rh factor, positive or negative, and many other blood group systems. Matching blood types made transfusions safe, and blood banks, pioneered by Charles Drew and others, allowed blood to be stored for emergencies.

Today blood donations save millions of lives in surgery, accidents and cancer treatment. Knowing your blood type is useful, and regular donors help keep blood supplies ready.
