Table 2 Accuracy of DPP tests in comparison to Trombley PCR (2014–2015)

From: Comparative performance study of three Ebola rapid diagnostic tests in Guinea

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)

  1. 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
