Conclusions: The clinical sensitivity of SARS-CoV-2 RT-PCR testing was only moderate at best. There are now several studies assessing their accuracy but as yet no systematic . The objective of our study was to evaluate the sensitivity and specificity of rapid antigen detection tests versus those of reverse transcriptase PCR (RT-PCR) using oral, anterior nasal, and nasopharyngeal swabs. A systematic review of the accuracy of covid-19 tests reported false negative rates of between 2% and 29% (equating to sensitivity of 71-98%), based on negative RT-PCR tests which were positive on repeat testing. Sensitivity was dependent upon the CT value for each sampling method. However, the reliability of the tests depends largely on the test performance and the respective sampling method. doi: 10.1136/bmjopen-2020-047110. 2022 Oct 27;19(21):14011. doi: 10.3390/ijerph192114011.
