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

  • b From reference 5.

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

  • d The IgG anti-HEV values for sera 62, 83, and 37 were 1.319, 0.899, and 0.746, 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).
