乙型肝炎病毒e抗原(HBeAg)为一种可溶性蛋白抗原,是乙型肝炎(HBV)活动性复制和有传染性的重要标志,HBeAg检测对于乙型肝炎的诊断、机体免疫状态的评价及病程的转归具有重要意义。目前广泛应用的酶联免疫吸附试验(ELISA)法存在不同的特异性和敏感性的差异,且结果仅可提示抗原是否存在。微粒子酶免法(MEIA)为一种新的检测方法,可半定量地检测HBeAg,MEIA法特异性强和敏感高,更
Hepatitis B virus e antigen (HBeAg) is a kind of soluble protein antigen which is an important marker of active replication and infectious of Hepatitis B (HBV). The diagnosis of HBeAg, the evaluation of immune status and the course of disease The outcome is of great importance. Currently widely used enzyme-linked immunosorbent assay (ELISA) there are different differences in specificity and sensitivity, and the results can only indicate the presence of antigens. Micronuclear enzyme immunoassay (MEIA) is a new detection method that can detect HBeAg semi-quantitatively. The MEIA method is characterized by strong specificity and high sensitivity.
