Table 2 Comparison of the kappa values, sensitivities and specificities obtained between the HC2 (gold standard) and the PCR-based techniques
PCR technique | Kappa value (CI 95%) | Sensitivity (CI 95%) | Specificity (CI 95%) |
|---|---|---|---|
GP-EIA | 0.71 (0.63–0.78) | 70,4% (62,1 – 78,7) | 96,2% (94,3 – 98,1) |
BSGP-EIA | 0.78 (0.71–0.84) | 77,4% (69,7 – 85,1) | 96,9% (95,3 – 98,5) |
pU | 0.63 (0.55–0.72) | 60,9% (52,0 – 69,8) | 96,5% (94,6 – 98,3) |
BSGP-EIA + pU | 0.82 (0.76–0.88) | 88,7% (82,8 – 94,6) | 95,1% (93,1 – 97,1) |
