Description
<p>Rapid diagnostic tests by antigen detection for diagnosing COVID-19 are widely used because they can be conducted easily and inexpensively. In this study, we compared the diagnostic performance of the SARS-CoV-2 antigen qualitative test kit “Quick NaviTM-COVID19 Ag” compared with that of the nucleic acid amplification test. As a result, both tests showed a concordance rate of 99.3%. Thirty cases showed both negative antigen qualitative and positive nucleic acid amplification test results. In many of the 30 cases, the Ct value tends to be high, and the amount of virus may be lower than the minimum detection sensitivity of the antigen qualitative test, and thus the results of the nucleic acid amplification test may not match those of the antigen qualitative test. On the other hand, seven cases showed both positive antigen qualitative and negative nucleic acid amplification test results. In all these seven cases, COVID-19 was confirmed to be negative, but a false positive result of the antigen qualitative test was obtained, the cause of which was not identified. From the above, it was clarified that “Quick NaviTM-COVID19 Ag” has sufficient performance as a SARS-CoV-2 antigen qualitative test. However, since false negative and positive results, which depend on the performance limits of the immunochromatography method, cannot be avoided, we should use it with sufficient attention to the characteristics of the test method.</p>
