Detection made by the three brands of COVID-19 test kits.
Table 1 shows the results of some quality characteristics for the three different test kits: DG Rapid, SD Rapid, and SS Rapid. The results indicate that the DG Rapid and SD Rapid groups had higher percentages of true positives (TPs) and lower percentages of false negatives (FNs) than the SS Rapid group. However, all test kits recorded a 100% true negative (TN) and zero cases of false positives (FPs), suggesting high specificity for all three kits.
