Figure 11–5. (A) The ABO blood types. Schematic representation of antigens on the

RBCs and antibodies in the plasma. (B) Typing and cross-matching. The A or B antiserum

causes agglutination of RBCs with the matching antigen. (C) Acceptable transfusions are

diagrammed and presuppose compatible Rh factors.
