Diagnostic performance of COVID-19 immunochromatographic rapid
test (ICT) kits.
Table 2 presents the sensitivity, specificity, positive
predictive value (PPV), negative predictive value (NPV), and overall
accuracy of the three different ICT kits.
The sensitivity of DG Rapid and SD Rapid was relatively high, with
values of 78.9% and 73.7%, respectively, while the sensitivity of SS
Rapid was lower at 50.0%. All three kits demonstrated 100.0%
specificity and 100% PPV. The NPVs of DG Rapid, SD Rapid, and SS Rapid
were 82.2%, 78.7%, and 66.1%, respectively.
The overall accuracy was highest for DG Rapid at 89.3%, followed by SD
Rapid at 86.7%, and SS Rapid at 74.7%. These results suggest that DG
Rapid and SD Rapid may be more effective than SS Rapid for detecting
SARS-CoV-2 RNA.
