原发性血小板减少性紫癜(下简称ITP)是一种自身免疫性疾病,诊断ITP应作血小板抗体测定。由于测定血清血小板抗体的方法缺点很多,现已逐渐被测定血小板结合IgG(下简称PAIgG)的方法所取代。我室根据抗人球蛋白消耗试验原理,采用间接血凝抑制法测定PAIgG,获得满意结果。现将初步实验及临床研究结果报告如下。 Primary thrombocytopenic purpura (hereinafter referred to as ITP) is an autoimmune disease, diagnosis of ITP should be measured for platelet antibodies. Due to the shortcomings of the method for the determination of serum platelet antibodies, it has been gradually replaced by platelet-bound IgG (PAIgG). According to the principle of anti-human globulin depletion test in our lab, PAIgG was determined by indirect hemagglutination inhibition and satisfactory results were obtained. Now the preliminary experimental and clinical research results are reported as follows.
