Reverse transcription–PCR (RT-PCR) remains the “gold standard” for identifying infected individuals ( 2). federal government continues to invest in SARS-CoV-2 testing, which remains essential as we begin to emerge from the pandemic ( 1). Easily accessible and widely distributed SARS-CoV-2 testing is a cornerstone of limiting the spread of the virus globally even as vaccines are distributed. The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), continues to threaten global public health. The performance may expedite isolation decisions or referrals for time-sensitive monoclonal antibody treatment in communities where timely COVID PCR tests are unavailable. IMPORTANCE The BinaxNOW rapid antigen COVID-19 test had a sensitivity of 87% in symptomatic and 71% asymptomatic individuals when performed by health care workers in a high-throughput setting. Nonetheless, rapid antigen testing quickly identifies positive among those with symptoms and/or close contact exposure and could expedite isolation and treatment. ![]() BinaxNOW has high accuracy among symptomatic individuals and is below the FDA threshold for emergency use authorization in asymptomatic individuals. Specificity was greater than 99% for all groups. Sensitivity was 82% (95% CI 66%, 91%) for asymptomatic individuals with potential exposure and 64% (95% CI 51%, 76%) for those with no exposure. ![]() It was higher in symptomatic (87% 95% CI 80%, 91%) than asymptomatic (71% 95% CI 61%, 80%) individuals. Overall test sensitivity compared with reference laboratory reverse-transcription PCR testing was 81% (95% confidence interval 75%, 86%). Most (89%) were asymptomatic, of whom 17% reported potential exposure. Participants were grouped by self-reported COVID-19 exposure and symptom status. We describe our implementation and assess performance of the BinaxNOW COVID-19 Antigen Test (Abbott Laboratories) in 6,099 adults at a self-referred walk-up testing site. ![]() Rapid antigen tests are simple to perform and provide results within 15 min.
