Allen等于1951年发现了Kidd血型系统,包含JKa、JKb、JK3等3个血型抗原。2年后,Plaut等在英国发现了相应的抗-JKb抗体。在临床上,以ABO和Rh血型系统引起的输血不良反应多见,由Kidd血型系统引起的输血反应较为罕见[1]。国内外有关报道显示,Kidd血型系统相关抗体主要通过激活补体引起迟发型溶血性输血反应,通过此种免疫途径引起的新生儿溶血病也曾报道过。以下 Allen was found in 1951 Kidd blood group system, including JKa, JKb, JK3 3 blood group antigen. Two years later, Plaut et al. Found a corresponding anti-Jbb antibody in the UK. Clinically, ABO and Rh blood group caused by adverse reactions of blood transfusion more common, caused by the Kidd blood group transfusion reaction is relatively rare [1]. Relevant domestic and foreign reports show that the Kidd blood group related antibodies mainly cause delayed hemolytic transfusion reaction by activating complement, and neonatal hemolytic disease caused by this immunization route has also been reported. the following
