应用ＥＬＩＳＡ抗体滴度测定法对２０例含戊型肝炎病毒ＩｇＧ型抗体（抗－ＨＥＶ－ＩｇＧ）阳性的健康献血员及５０例急性戊型病毒性肝炎（急性戊肝）病人血清进行了抗－ＨＥＶ－ＩｇＧ水平的检测。结果显示：健康献血员与急性戊肝病人血清抗－ＨＥＶ－ＩｇＧ几何平均滴度分别为１２２和１１２１（Ｐ＜０．０１）。当抗－ＨＥＶＩｇＧ抗体滴度＞１４０时，对诊断急性戊肝有重要的价值。
The serum of 20 patients with positive hepatitis E virus antibody (anti-HEV-IgG) and 50 patients with acute viral hepatitis E (acute hepatitis E) were tested for their anti- Detection of HEV-IgG levels. The results showed that the geometric mean titers of anti-HEV-IgG in healthy blood donors and acute hepatitis E patients were 122 and 1121, respectively (P <0.01). When anti-HEVIgG antibody titer> 140, the diagnosis of acute hepatitis E have important value.
