aELISA microplates were separately coated with purified immunodominant recombinant ORF2 polypeptide 459–607, and the truncated polypeptide 472–607. The OD450 value of the polypeptide 459–607 was denoted as OD459–607, and that of the polypeptide 472–607 was as OD472–607. Samples which showed OD459–607 ≥ 0.5 and the ratio of OD459–607 and OD472–607 > 2 or had the difference of OD459–607 minus OD472–607 > 0.5 were considered to be positive for anti-HEV IgM

bThe OD450 values of 0.263 or above were considered to be anti-HEV IgM positive according to the instruction of the Wantai ELISA
