Rh血型是最复杂的血型系统,D抗原是其最重要的抗原,临床意义仅次于ABO血型抗原。对绝大多数血型抗原而言,如果排除检测试剂和实验方法等因素的干扰,血清学试验能够明确显示血型抗原阳性或阴性,而D抗原则不同,由于红细胞(RBC)表面D抗原质和/或量的改变,在盐水介质加入抗-D血清无凝集或弱凝集,加入抗球蛋白(anti-human globulin,AHG)后,即间接抗球蛋白试验(indirect anti- Rh blood group is the most complex blood group system, D antigen is its most important antigen, clinical significance after ABO blood group antigen. For the vast majority of blood group antigens, if you exclude the interference of test reagents and experimental methods and other factors, serological tests can clearly show the positive or negative blood group antigen, and D antigen is different due to red blood cell (RBC) surface D antigen and / Or the amount of change in the saline medium by adding anti-D serum no agglutination or weak agglutination, adding anti-human globulin (AHG), the indirect anti-globulin test (indirect anti-
