Answer:
only the ABO antigens need to be compatible between donor and recipient
Step-by-step explanation:
An antigen is any molecule that is capable of inducing an immune response in the host (e.g., the coat protein of a pathogenic virus). The ABO blood group system is used to indicate the presence of one, both, or neither of A and B antigens on the surface of red blood cells. In blood transfusions, ABO antigens have to be compatible between donor and recipient. In consequence, it means that 1-donors of group A can donate blood to recipients with types A and AB (a recipient of group A can receive blood from a donor whose blood does not contain B antigen), 2-donors of group B can donate blood to recipients with types B and AB (a recipient of group B can receive blood from a donor whose blood does not contain A antigen); and 3- donors of group O can donate blood to recipients with types A, B, AB, or O (a recipient of group O blood can receive blood from a donor whose blood does not contain A and B antigens).
