  • a Numbers in boldface indicate that both samples of the pair were positive for IgM anti-HEV.

  • b From reference 6.

  • c PBS-treated and DTT-treated sera were tested on the same plate.

  • d IgG anti-HEV OD values for group 2 sera 137, 151, and 79 were 2.192, 2.480, and 2.577, respectively.

  • e The sample was diluted 1:100 before testing (final dilution of 1:10,000).

  • f The sample was diluted 1:10 before testing (final dilution of 1:1,000).
