Abo blood group

Abo blood group

(Science: haematology) The major human blood type system which describes the oligosaccharide glycoprotein antigens found on the surface of human blood cells.

According to the type of antigen present, a person may be assigned a blood type of a, B, ab or O. a second type of antigen, the rh factor, renders a positive or negative blood type. The abo blood group system is important because it determines who can donate blood to or accept blood from whom.

type A or ab blood will cause an immune Reaction in people with type B blood and type B and ab blood will cause a reaction in people with type A blood.

Conversely, type O blood has no a or B antigens, so people with type O blood are universal donors.

And since ab blood already produces both antigens, people who are type AB can accept any of the other blood types without suffering an immune Reaction. Classification of blood types in humans, a, B, ab and O. Blood transfusions of blood type O are suitable to transfer to all other blood groups. Blood groups tend to change in proportion in differing races, usually as a result of the geographical location in which the group has previously existed and consequently the ancestors who had such a blood group.
