自1973年以来,用对流免疫电泳法检测乙型肝炎表面抗原(以下简称HBsAg)。在西安地区其阳性检出率各型肝炎病人约为10—13%;健康人群约为3—5%。1977年,在医科院流研所的指导协助下,建立了放射免疫自显影和反向被动血凝二种敏感性较强的方法检测HBsAg,试图提高HBsAg的阳性检出率。经一年来的实践,经用两种方法(对流和放射)进行对比试验的共采各型肝炎病人和健康人群血液1,275人份,用三种方法(对流、放射、反向)对比的共采血306人份,现将检查结果总结如下。
Since 1973, the hepatitis B surface antigen (hereinafter referred to as HBsAg) has been detected by convective immuno-electrophoresis. In Xi’an, the positive rate of each type of hepatitis patients is about 10-13%; healthy population is about 3-5%. In 1977, with the help of the Institute of Flow Research Institute of Medical Sciences, two highly sensitive methods, radioimmunoimaging and reverse passive coagulation, were established to detect HBsAg in an attempt to increase the positive detection rate of HBsAg. After a year of practice, a total of 1,275 blood samples were collected from all hepatitis patients and healthy people by two methods (convection and radiation) and compared with three methods (convection, radiation, reverse) 306 people, now the inspection results are summarized below.
