D抗原遮断引起Rh(D)定型困难的分析

D Antigen Interrupt Cause Difficulties Rh(D) to Finalize the Design Analysis

目的正确鉴定新生儿的血型,找出新生儿溶血病原因,制定合理的治疗方案。方法用直抗、游离试验、放散试验、不规则抗体筛选及抗体鉴定试验鉴定其Rh(D)血型。结果该患儿为B型Rh(D)阳性,由母体Ig G抗-D抗体引起新生儿溶血。结论由于抗-D抗体致敏了红细胞而误认为Rh(D)血型为阴性。

Objective To correct identification of neonatal blood types, and identify the reasons for newborns hemolytic disease, formulate reasonable treatment scheme. Methods Using direct resistance, free trial, tossing in the test, irregular antibody screening antibody evaluation test and evaluation the Rh blood type （D）. Results The children with positive for type B Rh （D）, caused by anti-D matrix IgG antibody neonatal hemolysis. Conclusion Due to the anti-D sensitization of red blood cells and antibodies for Rh negative blood type （D）.
