Investigations on six males with naturally occurring Rh antibodies are described. In two subjects in whom the antibody (one anti-E and one anti-D) could be detected only by a two-stage papain technique, the survival of incompatible red cells was normal. In the remaining four subjects, the antibodies (two anti-E and two anti-D) could be detected by the indirect antiglobulin test and, in these, incompatible red cells were destroyed at an accelerated rate; in two of the subjects, 75-99% of the cells were cleared within 24 h; in the other two, 50% of the cells were cleared within 24 h and the remaining cells were cleared far more slowly. All six antibodies were mainly or wholly IgG; a clear-cut immune response was observed in only one case.
