目前乙型病毒性肝炎抗原抗体系统的五项试验及甲型肝炎病毒IgM型抗体检测在国内已逐渐开展。本文参考有关资料,对这方面的研究进展及临床意义作一介绍,仅供参考。一、甲型肝炎病毒抗原抗体系统 1973年芬斯通等首先用免疫电镜从甲型肝炎急性期病人的大便滤液中检出病毒颗粒,即甲型肝炎病毒颗粒(HAV)又称为甲型肝炎病毒抗原(HAAg)。HAV在临床症状出现前6～7天浓度最高,而在黄疸
At present, the five tests of hepatitis B antigen antibody system and the detection of hepatitis A virus IgM antibody have been carried out in China. This article refers to the relevant information, research progress in this area and clinical significance of an introduction, for reference purposes only. First, the hepatitis A virus antigen antibody system In 1973, Festoon et al. First used immunoelectron microscopy to detect virions in the stool filtrate from patients with acute hepatitis A, ie, hepatitis A virus particles (HAV), also known as hepatitis A Viral antigen (HAAg). HAV 6 to 7 days before clinical symptoms appear the highest concentration, while in jaundice
