Table 2: Comparison of performance of ICT as rapid screening test of LF and the true status of disease as determined by Thick Blood Film/Microscopy.
Test Positive | True Positive (TP ) | False Positive (FP ) | PPV |
77 | 34 (36.96%) | 43 (21.29%) | = (TP )/(TP ) + (FP ) = 0.442 |
Test Negative | False Negative (FP ) | True Negative (TN ) | NPV |
217 | 58 (63.04%) | 159 (78.71%) | = (TN)/(FN ) + (TN ) = 0.733 |
Sensitivity = (TP)/(TP) + (FN ) = 0.369 (44.16%) |
Specificity = (TN)/(FP) + (TN ) = 0.787 (73.27%) |
