Table 2.

Accuracy of DPP tests in comparison to Trombley PCR (2014–2015)

Results of DPP Assays Relative to PCR (n = 205)
All values are percentages with 95% confidence intervals
Fever Panel [95%CI] Ebola [95%CI] Ebola Malaria [95%CI]
Sensitivity 89.91 (82.3–94.6) 77.06 (67.8–84.3) 77.98 (68.8–85.1)
Specificity 90.63 (82.5–95.4) 91.67 (83.8–96.1) 95.83 (89.1–98.7)
% Discordant (n) 9.76 (20) 16.1 (33) 13.7 (28)
Accuracy 90.24 (85.33–93.94) 83.9 (78.14–88.65) 86.3 (80.87–90.73)

The measures of accuracy were calculated as follows:

Measure Formula
Sensitivity (TP/(TP+ FN)) * 100%)
Specificity (TN/(FP+TN)) * 100%)
Accuracy ((TP+TN)/(TP+TN+FP+FN))*100%)
TP = # True Positives; FP = # False Positives; TN=# True Negatives; FN=# False Negatives
