The performance of this test has not yet been clinically validated for use in patients without signs and symptoms of respiratory infection or for serial screening applications, and performance may differ in these populations. When the pretest probability for receiving positive test results for SARS-CoV-2 is elevated (e.g., in symptomatic persons or in persons with a known COVID-19 exposure), a negative antigen test result should be confirmed by NAAT (1). This type of knowledge could help support research about how the virus spreads within communities and immune responses to vaccines. Homology for KHU1 and MERS-CoV is relatively low, at 37.8% across 95% of the sequence and 57.14% across 87% of the sequence, respectively. Positive agreement of the BinaxNOW compared a PCR assay was "99/117, 84.6% (95% CI: 76.8% . If you have the virus and are asymptomatic, this percentage dips to about 44% to 70%.

The BinaxNOW COVID-19 Antigen Self-Test is a rapid test that uses a shallow nasal swab sample to check for the presence or absence of proteins from the virus that causes COVID-19. The prevalence of having SARS-CoV-2 real-time RT-PCR positive test results in this population was moderate (8.7% overall; 4.7% for asymptomatic participants); administering the test in a lower prevalence setting will likely result in a lower PPV. Among 11 participants with antigen-negative, real-time RT-PCRpositive specimens with positive viral culture, five were symptomatic and six asymptomatic. In this evaluation, using real-time RT-PCR as the standard, the sensitivity of the BinaxNOW antigen test was lower among specimens from asymptomatic persons (35.8%) than among specimens from symptomatic persons (64.2%).
