The urgent need to scale up access to COVID-19 testing in Nigeria has led to the government¡¯s introduction of the use of COVID-19 Ag rapid diagnostic test (RDT) across various settings in the country. However, field performance evaluation of the rapid SARS-CoV-2 antigen detection test is required to be conducted periodically and compared with the gold standard real-time reverse transcription-polymerase chain reaction (RT-PCR) test for diagnosis of COVID-19 cases. Design: A prospective COVID-19 screening and un-blinded verification of the performance of the STANDARD Q COVID-19 Ag test kit. Setting: The rapid SARS-CoV-2 antigen detection test, StandardTM Q COVID-19 Ag kit was compared with the RT-PCR test for detection of SARS-CoV-2 in nasopharyngeal samples for COVID-19 screening from persons and personnel attending a national youth camp orientation exercise during the second wave of the COVID-19 outbreak (January to March 2021) in Ondo state, southwest Nigeria. Participants: Three hundred fifty-one persons and personnel were screened for COVID-19 infection. Results: Of 351 respondents screened, 68 (19.4%) were positive, and 264 (75.2%) were negative for both COVID-19 Ag RDT and RT-PCR assay. The rapid SARS-CoV-2 antigen detection test¡¯s sensitivity and specificity were 78.16% (95% CI = 68.02% - 86.31%) and 100.0% (95% CI = 98.61% - 100.0%), respectively and the diagnostic accuracy was 94.59% (95% CI: 92 - 97). Respondents that were symptomatic had a higher test sensitivity of 78.6% (49.2 - 95.3) compared to those without symptoms 78.1% (66.9 - 86.9) (p < 0.05). Conclusions: Our study shows evidence that StandardTM Q COVID-19 Ag kit can be an appropriate rapid antigen test that could be used to screen for positive COVID-19 tests to guide decision-making for clinical management of persons infected with COVID-19, especially for closed settings and other clinical care settings. %K SARS-CoV-2 %K COVID-19 Rapid Antigen %K RT-PCR %K Sensitivity %K Nigeria %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=120691
