Allo-anti-P1 in a P1-positive person.
An allo-anti-P1 antibody is reported in an elderly Caucasian male with P1+ red cells. There was no suggestion that the antibody was causing haemolysis. The case suggests that a slight structural variation may exist in the patient's B antigen giving a serological false-positive response when typed with reagent anti-P1, or that the patient's anti-P1 is directed against a determinant absent in the patient's own antigen structure.
