If a type B-negative patient is accidentally given type A-positive blood, the patient's antibodies will recognize the donor's A antigens as foreign and begin to attack the donated erythrocytes. This can result in a severe immune reaction, known as a hemolytic transfusion reaction, which can be fatal if not treated promptly.
