The levels of serum IgG antibody to hepatitis E virus (anti-HEV-IgG) was detected in serum specimens from 50 patients with acute sporadic hepatitis E and 20 healthy donors who were positive for anti-HEV-IgG by ELISA titration. The results showed that the level of anti-HEV-IgG in acute hepatitis E patients was significantly higher than that in healthy donors and the average titer is 1:121 and 1:22, respectively (P < 0.01). So acute viral hepatitis E should be diagnozed when the titer of anti-HEV-IgG was over 1:40.
采用ELISA滴定法检测了50例急性散发性戊型肝炎患者和20例抗戊型肝炎病毒IgG（anti-HEV-IgG）阳性健康献血者血清标本中anti-HEV-IgG水平。结果显示，急性戊型肝炎患者的anti-HEV-IgG水平显著高于健康献血者，平均滴度分别为1:121和1:22（P<0.01）。因此，当anti-HEV-IgG滴度超过1:40时，应诊断为急性戊型病毒性肝炎。
