Diagnostic specificity of the Panbio and NovaLisa dengue IgG ELISAs.
| YFV-Vaccinated | JEV-Vaccinated | |||
|---|---|---|---|---|
| Panbio Dengue IgG ELISA (N = 59) | NovaLisa Dengue IgG ELISA (N = 59) | Panbio Dengue IgG ELISA (N = 31) | NovaLisa Dengue IgG ELISA (N = 29) | |
| Positive results | 4 1 | 13 1 | 1 2 | 3 2 |
| Equivocal | 2 | 3 | 0 | 1 |
| Negative | 53 | 43 | 30 | 25 |
| Specificity (%, 95% CI) 3 | ||||
| With DENV-neutralizing sera | 93.3 (83.83–97.4) | 78.0 (65.9–86.7) | 96.8 (83.8–99.4) | 89.7 (73.7–96.5) |
| W/o DENV-neutralizing sera | 98.2 (90.6–99.7) | 88.2 (70.2–90.0) | 100 (88.7–100) | 92.9 (77.4–98.0) |
1 Three sera neutralized DENV; 2 one serum neutralized DENV; 3 specificity was calculated based on all sera (with) or after subtraction of DENV-neutralizing sera (w/o); equivocal results were counted as negative. CI: confidence interval.
