TABLE 6.
Overall diagnostic accuracy and sensitivity of ELISA for DENV NS1 and Platelia dengue NS1 Ag ELISAa
| ELISA | No. of serum samples positive for NS1 | Sensitivity (% [95% CI]) | Specificity (% [95% CI]) | Accuracy (% [95% CI]) | PPV (% [95% CI]) | NPV (% [95% CI]) |
|---|---|---|---|---|---|---|
| ELISA for DENV NS1 | 56 | 84.85 (73.9–92.49) | 100 (95.49–100) | 93.15 (87.76–96.67) | 100 (93.63–100) | 88.89 (80.51–94.54) |
| Platelia dengue NS1 Ag ELISA | 55 | 83.33 (72.13–91.38) | 100 (95.49–100) | 92.47 (86.92–96.18) | 100 (93.51–100) | 87.91 (79.4–93.81) |
a
True status was determined for 66 patients with dengue virus infections and 80 patients with non-dengue virus infections. PPV, positive predictive value; NPV, negative predictive value.
