ABO Blood Group
A blood type is a classification system that allows healthcare providers to determine whether one person's blood is compatible with someone else's. In the ABO system, type A red blood cells carry the A antigen, type B carry the B antigen, type AB carry both, and type O carry neither.
Why it matters: Blood transfusions and organ transplants depend on donors and recipients having compatible blood types. If blood is received from a donor whose blood cells carry antigens the body does not recognise, the immune system may attack the donated red blood cells.

What is ABO Blood Group?
A blood type is a classification system that allows healthcare providers to determine whether one person's blood is compatible with someone else's. In the ABO system, type A red blood cells carry the A antigen, type B carry the B antigen, type AB carry both, and type O carry neither.
What might a high or low ABO Blood Group mean?
Blood transfusions and organ transplants depend on donors and recipients having compatible blood types. If blood is received from a donor whose blood cells carry antigens the body does not recognise, the immune system may attack the donated red blood cells.
