目的探讨对流免疫电泳试验在肝片吸虫病诊断中的应用。方法用对流免疫电泳试验(CIET)检测肝片吸虫患者、肝片吸虫病兔、正常兔、血吸虫病兔和血吸虫患者血清的抗体。结果以CIET检测肝片吸虫患者和病兔血清中的抗体,阳性率分别为90.3%和92.3%。同时检测正常兔、血吸虫病兔和血吸虫病人血清,皆无沉淀线形成,阴性反应。结论 CIET用于肝片吸虫病临床诊断具有较好的特异性。 Objective To investigate the application of convective immunity electrophoresis in the diagnosis of hepatic fistula. Methods The antiserum of patients with Fasciola hepatica, Fasciola hepatica, normal rabbits, schistosomiasis rabbits and schistosomiasis were detected by convective immunity electrophoresis (CIET). Results CIET was used to detect the antibody in the serums of Fasciola hepatica and rabbits, the positive rates were 90.3% and 92.3% respectively. Simultaneous detection of normal rabbits, schistosomiasis rabbits and schistosomiasis patients serum, no precipitation line formation, negative reaction. Conclusion CIET for the clinical diagnosis of hepatic fistula has a good specificity.
