目前认为e系统的检测对乙型肝炎的流行病学、临床、预后及防治方面都有较重要的意义。国内多般采用双向琼脂免疫扩散法,我们为了探讨提高e系统阳性检出率,建立了对流免疫电泳法,并进行对比试验,现将结果报告如下: 材料与方法一、材料: 1、标本来源;系我省进行病毒性肝炎流行病学调查收集的696份血清标本。 (1)经反向被动血凝(RPHA)法证实HBsAg阳性365份。 (2)经被动血凝(PHA)法证实抗HBs阳性41份。 Currently, the detection of e-system is of great significance for the epidemiology, clinical, prognosis and prevention and treatment of hepatitis B. We generally use two-way agar immunodiffusion method, we in order to explore to improve the positive detection rate of e system, the establishment of the convection immuno-electrophoresis and comparative tests, the results are reported as follows: Materials and methods First, the material: 1, specimen source ; Department of our province for viral hepatitis epidemiological survey collected 696 serum samples. (1) HBsAg positive by reverse reverse hemagglutination (RPHA) method confirmed 365 copies. (2) 41 positive anti-HBs were confirmed by passive hemagglutination (PHA).
