A patient with transient autoanti-Jka.

We report a patient with an erythrocyte autoantibody in whose serum a broadly reactive antibody was transiently replaced by a monospecific autoanti-Jka. On preoperation evaluation, a 49-year-old man, who had never been transfused, exhibited both a positive antibody screen and a positive direct antiglobulin test. Although a broadly reactive antibody had been present 2 years earlier, only anti-Jka was found in the serum on preoperative testing.
