Sensitivity and specificity of IFA and ELISA assay based on two-class model with traditional latent class analysis*
| Assay | % Sensitivity (95% CI) | % Specificity (95% CI) |
|---|---|---|
| IFA-IgG | 96 (95,97) | 95 (92, 97) |
| ELISA-IgG | 94 (92, 96) | 96 (92, 98) |
| IFA-IgM | 66 (55, 76) | 99 (98, 100) |
| ELISA-IgM | 93 (87, 100) | 90 (87, 93) |
IFA = immunofluorescent assay; ELISA = enzyme-linked immunosorbent assay; IgG = immunoglobulin G; CI = confidence interval; IgM = immunoglobulin M.
