目的研究孕妇血清中IgG抗A(B)效价与新生儿溶血病关系。方法用直接法:直抗试验、红细胞抗体游离试验、红细胞抗体释放试验。结果ABO-HDN的发病率随母体IgG抗A(B)的水平升高而递增。结论对怀孕20周的孕妇进行产前的IgG抗A(B)效价检测,更能准确地预报ABO-HDN的发生,从而指导临床采取有效的预测和治疗措施。
Objective To study the relationship between serum IgG anti-A (B) titer and hemolytic disease in newborns. Methods using direct method: direct anti-test, erythrocyte antibody free test, erythrocyte antibody release test. Results The incidence of ABO-HDN increased as the level of maternal IgG anti-A (B) increased. Conclusions Prenatal IgG anti-A (B) titer test can be used to predict the occurrence of ABO-HDN accurately in pregnant women of 20 weeks of pregnancy, so as to guide the clinical practice of effective prediction and treatment measures.
