5.HBeAg:常于HBsAg出现后即可检出,于HBsAg消失前转阴,HBeAg若持续3月以上则提示为慢性肝病。HBeAg(+)提示HBV在肝内活跃的复制,故可视为HBV传染的灵敏的指标。HBeAg(+)者之SGPT常显著高于HBeAg(-)者及检出率以慢活肝时最高,故HBeAg(+)时可视为病情较重及有慢性化趋向。HBeAg有e1、2、3三种亚型,HBeAg(+)中e_3检出率可达44％,e_3(+)者常伴DNAP增高等传染性标记,
5.HBeAg: often appear after the occurrence of HBsAg, HBsAg disappeared before the negative, HBeAg if continued for more than 3 months is prompted for chronic liver disease. HBeAg (+) prompts the active replication of HBV in the liver, it can be regarded as a sensitive indicator of HBV infection. The SGPT of HBeAg (+) patients is often significantly higher than that of HBeAg (-) and the detection rate is the highest among those with slow living liver, so HBeAg (+) can be regarded as severe and chronic. HBeAg e1,2,3 three subtypes, HBeAg (+) e3 detection rate of up to 44%, e3 (+) often accompanied by DNAP increased infectious markers,
