How does antigen/antibody reaction pertain to blood types?
Explanation
Blood must be typed and cross-matched in order to administer compatible donor blood. The blood type is determined by proteins called antigens present on the surface of RBCs. Blood type is inherited. The major groupings of concern in surgery are ABO and Rh. Patients may be type A, B, AB, or O. Type A blood contains the A antigen, type b has the B antigen, type AB contains both, and type O blood has neither. Rh –positive blood contains the Rh antigen and Rh-negative blood has no Rh antigen present. Each person also has the corresponding antibody present in his or her plasma. If a type A blood is administered to a type B patient, the recipient’s antibodies will attack the donor RBCs, causing potentially fatal transfusion reactionsRate this question:
- 19.
