自身免疫性溶血性贫血(autoimmune hemolytic anemia,AIHA)为患者自身抗体引起红细胞破坏的1种溶血性贫血。AIHA发生率3/(100 000·年),多数为温抗体,少数为冷抗体。《临床输血技术规范》规定红细胞输注前必须做血型鉴定(ABO,RhD)、抗体筛查和交叉配血3项试验,而AIHA患者体内存在的自身抗体不仅凝集自身红细胞,也凝集所有供
Autoimmune hemolytic anemia (AIHA) is a type of hemolytic anemia in patients with autoantibodies that cause destruction of red blood cells. AIHA incidence of 3 / (100 000 years), the majority of warm antibodies, a few cold antibodies. The Clinical Transfusion Technical Specification stipulates that three types of blood test (ABO, RhD), antibody screening and cross-matching should be performed before transfusion of erythrocytes. However, autoantibodies existing in AIHA patients not only agglutinate their own erythrocytes but also agglutinate all
