Development and Detection of Kidd Antibodies.

Kidd antibodies have a reputation for causing hemolytic transfusion reactions and hemolytic disease of the fetus and newborn. We present a case of an untransfused male patient who developed anti-Kidd(a) (Jk(a)) antibodies after receiving an allogenic renal transplant. The formation of this antibody was associated with exposure to the Kidd antigen expressed on the tubular epithelium of the transplanted kidney.
