自从HBsAg被发现以来,人们对HBV的研究有了很大进展。到目前为止,已先后证明与HBV相关的有5个抗原抗体系统。现就其临床意义,概述如下: 一、乙型肝炎表面抗原-抗体系统 1.乙型肝炎表面抗原(HBsAg):HBsAg为乙肝病毒(HBV)的外壳,为三种形态的颗粒所共有,因为这一共同的抗原存在于其表面,故名为表面抗原。 HBsAg阳性的临床意义:(1)有助于乙型肝炎的早期诊断:HBsAg是感染了HBV的一个特异性标志,血清内检出HBs
Since the discovery of HBsAg, great progress has been made in the study of HBV. So far, it has been proved that there are five anti-HBV antibody system. Now on its clinical significance, summarized as follows: A, hepatitis B surface antigen - antibody system 1. Hepatitis B surface antigen (HBsAg): HBsAg is the outer shell of hepatitis B virus (HBV), the three forms of particles are common, because This common antigen exists on its surface and is therefore called a surface antigen. The clinical significance of HBsAg positive: (1) contribute to the early diagnosis of hepatitis B: HBsAg is a specific marker of HBV infection, serum HBs detected
