Among 3,302 persons tested for SARS-CoV-2 by BinaxNOW Rapid SARS-CoV-2 antigen detection assay in a community setting with 7.2% prevalence, rapid assay sensitivity was 100%, 98.5%, and 89% using RT-PCR Ct thresholds of 30, 35 and none, respectively. The assay maintained high sensitivity performance across ages and those with and without symptoms. Assay specificity was 99.9%. The median time from on-site registration to electronic results notification of a positive rapid antigen test was 62 minutes (IQR: 47-82 minutes).
