Hemolytic Transfusion Reactions Associated with the Kidd Antibody (JkA)

Abstract
ALTHOUGH the Kidd antibody (Jka) was originally described as a cause of hemolytic disease in the newborn,1 a few well documented cases of hemolytic transfusion reactions secondary to anti-Jka have been reported.2 3 4 5 6 7 These are of clinical importance because anti-Jka is frequently difficult to detect in the recipient's blood, and the crossmatch can appear to be normal.This report describes 2 patients with hemolytic reactions secondary to anti-Jka that followed transfusions with apparently compatible blood.Case ReportsCase 1. C.H., a 50-year-old man, was first seen at Harbor General Hospital on November 21, 1965, with a diagnosis of Hodgkin's disease. . . .
