Diagnostic performance of the SH-LAMP-LFD protocol.
| SH-LAMP-LFD | Mtb status by reference assay | |
|---|---|---|
| Positive | Negative | |
| Positive | 74 (TP) | 0 (FP) |
| Negative | 0 (FN) | 30 (TN) |
| % | 100 (sensitivity) | 100 (specificity) |
| % | 100 (accuracy of SH-LAMP-LFD result) | |
Sensitivity = [TP/(TP + FN)]*100, specificity = [TN/(TN + FP)]*100.
Accuracy = [(TP + TN)/(TP + TN + FN + FP)]*100.
TP true positive, FP false positive, FN false negative, TN true negative.
