近年来,间接红细胞凝集试验诊断血吸虫病已逐步在现场推广应用。经湖南、湖北等地现场实验证明,它是血吸虫病综合查病中一项有效的免疫学诊断方法,但亦存在着假阳性、假阴性等问题。为了逐步摸清这些问题,我们于1977年10月在鹤峰县对血吸虫卵抗原致敏红细胞与肺吸虫病有无交叉反应等问题,进行了现场实验研究,结果如下:病例的选择一、肺吸虫病现症病例选择在有食生蟹史、皮内试验阳性、嗜酸粒细胞增多、有游走性皮下结节、胸透有典型病变、对流免疫电泳阳性及肺吸虫成虫抗原致敏红细胞凝集试验阳性这7项指标中,有3项以上阳性者,作为肺吸虫病现症病例,共选择52例作为试验对象。二、在鹤峰县人民医院对100例门诊病人(已排
In recent years, indirect hemagglutination test for the diagnosis of schistosomiasis has been gradually applied in the field. It has been proved by field experiments in Hunan and Hubei that it is an effective method for immunological diagnosis of schistosomiasis, but there are also some problems such as false positive and false negative. In order to find out these problems step by step, we carried out a field experiment on the cross-reaction of erythrocytes and paragonimiasis caused by schistosome egg antigen in Hefeng County in October 1977. The results are as follows: Trematosis disease cases in the history of eating crabs, intradermal test positive, eosinophilia, there are migratory subcutaneous nodules, chest X-ray typical lesions, convective immunity electrophoresis and paragonimiasis adult antigen-sensitized erythrocytes Agglutination test was positive in the seven indicators, there are three or more positive, as the case of paragonimiasis, a total of 52 cases were selected as the test object. Second, in Hefeng County People’s Hospital of 100 cases of outpatients (already ranked
