乙型病毒性肝炎是危害人类健康的一种主要传染病。乙型肝炎病毒(HBV)感染后,血清中可留下HBV标志物,现将检测其临床意义浅述如下。 (一)乙型肝炎表面抗原(HBsAg) HBsAg是HBV的外壳蛋白,它不含病毒的核酸成分,HBsAg阳性是机体感染HBV的标志,但不肯定有传染性。传染性取决于病毒复制的标志—HBeAg阳性、抗HBcIgM阳性、DNA—P活力升高、HBV—DNA的存在。虽说表面抗原本身没有传染性,但因常与HBV同时存在,故临床上常被认为是传染性指标之一。 HBsAg阳性也并不肯定患病。急性、慢性乙
Hepatitis B virus is a major infectious disease that endangers human health. Hepatitis B virus (HBV) infection, the serum HBV markers may be left behind, the detection of its clinical implications are as follows. (A) Hepatitis B surface antigen (HBsAg) HBsAg is the coat protein of HBV, which does not contain the virus nucleic acid composition, HBsAg positive is a sign of HBV infection in the body, but not necessarily contagious. Infectivity depends on the sign of viral replication-HBeAg-positive, anti-HBcIgM-positive, elevated DNA-P activity, and the presence of HBV-DNA. Although the surface antigen itself is not contagious, but often coexist with HBV, it is often considered clinically one of the infectious indicators. HBsAg-positive is not affirmed. Acute, chronic B
