本文介绍应用检测AFP 普查原发性肝癌的概况,比较不同检测方法的灵敏度,并通过观察APF 含量的动态变化,探讨肝癌的早期诊断,鉴别假阳性病例,评价治疗效果和估计病情预后,对五年来的AFP 检测工作做一总结。检测方法本文最初采用琼脂双向扩散法(简称扩散法),1972～1973年加用对流免疫电泳(简称对流法),1974年以后均采用血球凝集试验(简称血凝法)初检,凡血凝1∶10(++)以上者列为阳性,再以对流法复测,用放射免疫火箭电泳 This article describes the application of detection of AFP general survey of primary liver cancer, compared the sensitivity of different detection methods, and by observing the dynamic changes of APF content, to explore the early diagnosis of liver cancer, identify false positive cases, evaluate the therapeutic effect and prognosis of the disease, AFP detection work done a summary. Detection method This article initially used agar two-way diffusion (referred to as diffusion), 1972 to 1973 plus the use of convective immunity electrophoresis (referred to as convection method), after 1974 are used hemagglutination test (referred to as hemagglutination test) 1:10 (++) These were listed as positive, and then retest by convection, radioimmunoassay rocket electrophoresis
