【摘要】 <正> 间接红细胞凝集试验(简称间接血凝试验,IHA)是早已应用于诊断病毒、细菌性疾病以及寄生虫病的方法。国外Kagan(1955)首先应用于动物接种曼氏血吸虫后的实验研究,国内自1959年以来先后均有报告,并已证实具有高度的敏感性和特异性,其优越性已为国内外学者所公认,但由于试验用红细胞的致敏手续较繁,致敏后的红细胞抗原不能长期保存,因而使用上受到限制。 Bing等(1967)在不断改进试验的基础更多还原

【Abstract】 At present,the indirect hemagglutination (IHA) test is most widely used for diagnosis of schistosomiasis.Our experiments have confirmed its usefulness.It gave approximately 97.7% positive reaction in patients with schistosomiasis.The procedure is more sensitive,less timeconsuming and easier to perform than the other serological reactions,such as the circumoval precipitin test,the cercarien-huellen reaction,counter-current electophoresis,etc.It should be emphazised that satisfactory result could be obtained,only if the erythrocytes used for this test are pretreated properly at 4℃ with glutaraldehyde and appropriate concentration of tannic acid,before the to be.tested antigen is absorbed on the erythrocytes.The major shortcoming of the test which requires further study is that it is less specific,because it tends to react with paragonimus antigen easily.更多还原
