Individuals with type O blood can give to anyone, as their blood contains no antigens. They can, however, accept blood only from other type O persons.


Individuals with type A blood can give to other individuals with type A blood and individuals with type AB blood. Individuals with type A blood can only receive blood from type A and type O individuals.


Type B individuals can donate blood to other B and AB individuals. Individuals with type B blood can only accept blood from type B and type O individuals.

How Blood Typing is Performed.

Blood samples are mixed with antibodies that attack both types A and B blood to determine your blood type. Your blood cells don’t mix well with antibodies that attack type A blood, so you have type B blood. It will then be mixed with anti-Rh serum, and your blood will be sent to a lab. In this case, the anti-Rh serum caused your blood cells to clump together. This means that you have blood with the Rh group.
