HEV antibody detection constitutes the main screening test for HEV infection. The aim of this study is to compare the sensitivity and specificity of four techniques: LIAISON MUREX DiaSorin anti-HEV IgG and anti-HEV IgM assays, Hepatitis E VIRCLIA IgM and IgG monotests, WANTAI HEV-IgM and IgG ELISA and VIDAS anti-HEV IgM and IgG tests in five panels of samples configurated according to the immunoblot (RecomLine, Mikrogen, Neuss, Germany). Anti-HEV IgM sensitivity in the acute phase was 100% in all techniques, while sensitivity, including the immediate convalescence phase, was 96.74% for LIAISON, 83.14% for VIRCLIA, 84.78% for WANTAI and 88.04% for VIDAS. Anti-HEV IgM specificity was 100% for both LIAISON and VIRCLIA. Anti-HEV IgM WANTAI agreed with VIRCLIA with a good Kappa coefficient (κ = 0.71). Anti-HEV IgG post-infection sensitivity was 100% for LIAISON, VIDAS and VIRCLIA and 99% for WANTAI. Anti-HEV IgG specificity reached 97.17% for LIAISON and 88.68% for VIRCLIA. Our results demonstrated a better capacity of LIAISON MUREX anti-HEV IgM than that of competitors for detecting acute infections as well as accurate anti-HEV IgG results and in how to resolve them.
戊型肝炎病毒（HEV）抗体检测是HEV感染的主要筛查试验。本研究旨在比较四种技术的敏感性和特异性：LIAISON MUREX DiaSorin抗HEV IgG和抗HEV IgM检测、戊型肝炎病毒VIRCLIA IgM和IgG单项检测、万泰HEV-IgM和IgG酶联免疫吸附测定（ELISA）以及VIDAS抗HEV IgM和IgG检测，这四种技术针对按照免疫印迹法（德国诺伊斯市Mikrogen公司的RecomLine）配置的五组样本进行检测。在急性期，所有技术检测抗HEV IgM的敏感性均为100%，而在包括恢复期早期阶段在内的整个过程中，LIAISON检测的敏感性为96.74%，VIRCLIA为83.14%，万泰为84.78%，VIDAS为88.04%。LIAISON和VIRCLIA检测抗HEV IgM的特异性均为100%。万泰抗HEV IgM与VIRCLIA的检测结果一致性良好，卡帕系数（κ）为0.71。感染后抗HEV IgG的敏感性，LIAISON、VIDAS和VIRCLIA均为100%，万泰为99%。LIAISON检测抗HEV IgG的特异性达到97.17%，VIRCLIA为88.68%。我们的结果表明，在检测急性感染方面，LIAISON MUREX抗HEV IgM的能力优于其他同类产品，并且其抗HEV IgG检测结果准确。
