Blood type A has anti-B antibodies in its plasma. This means that individuals with type A blood can react against type B blood cells, as their immune system recognizes the B antigens as foreign. Therefore, type A blood is compatible for transfusion with type A and type O blood, but not with type B or AB blood.

Each blood type has it's identifying proteins, and will reject blood with the wrong proteins. Type A blood is anti-B, type B blood is anti-A, type O blood has both, and type AB blood has neither. Imagine if someone with AB blood tried to donate to someone with A. AB blood has identifying proteins A and B. The type A blood would recognize the B proteins and kill the cells. The same thing would happen with B, which would recognize the A proteins and kill the cells. Type O blood would recognize and reject both the A and B proteins and reject them. However, if someone who is type AB gives to AB people, their blood does not destroy neither protein A nor B, so it would accept it.
A type
Usually type A people have naturally occuring anti-B in circulation.
blood type A have antigen A and anti body B blood type B have antigen B and anti body A blood type AB have antigens A and B and do not have anti body blood type O do not have antigen but have anti bodies A and B
The four blood types are a, b, ab, and o. O is known as the universal donor because it has no proteins, so it can be given to any other blood type without harming it. AB is known as the universal recipient because it can receive any other blood type but can't give any away because it has a mixture of proteins.
blood type A
If there is no agglutination (clotting) at either the Anti-A or Anti-B fields on a test plate, then the blood type will be Type O.
The anti-clumping protein in blood type A is anti-B antibodies. These antibodies are produced by individuals with blood type A to protect against foreign blood cells that have B antigens. They help prevent clumping or agglutination when incompatible blood types are mixed.
Blood Type 'O': Red Blood cells have neither A-antigen, nor B-antigen but generates both Anti-A and Anti-B antibodies - Blood Type 'A': Red blood cells have the A-antigen which generates the Anti-B antibodies Blood Type 'B': Red blood cells have the B-antigen and generate Anti-A antibodies The lack of antigen explains why Type "O" can safely donate to Type "A" and Type "B". The Anti-A and Anti-B antibodies generated by Type "O" is the reason "O" cannot receive donations from Type "A" or Type "B".
