摘要：SummaryAs the emergence of SARS-CoV-2 variants brings the global pandemic to new levels, the performance of current rapid antigen tests against variants of concern and interest (VOC/I) is of significant public health concern. Here, we report assessment of the Abbot BinaxNOW COVID-19 Antigen Self-Test. Using genetically sequenced remnant clinical samples collected from individuals positive for SARS-CoV-2, we assessed the performance of BinaxNOW against the variants that currently pose public health threats. We measured the limit of detection of BinaxNOW against various VOC/I in a blinded manner. BinaxNOW successfully detected the Omicron (B.1.1.529), Mu (B.1.621), Delta (B.1.617.2), Lambda (C.37), Gamma (P.1), Alpha (B.1.1.7), Beta (B.1.351), Eta (B.1.525), and P.2 variants and at low viral concentrations. BinaxNOW also detected the Omicron variant in individual remnant clinical samples. Overall, these data indicate that this inexpensive and simple-to-use, FDA-authorized and broadly distributed rapid test can reliably detect Omicron, Delta, and other VOC/I.Graphical abstractDisplay OmittedHighlights•Pooled remnant clinical samples with variants of concern are tested using BinaxNOW•BinaxNOW detects live and heat-inactivated virus in pooled and individual samples•BinaxNOW sensitivity slightly lower against Omicron variant in laboratory tests•BinaxNOW remains a useful public health tool to combat the COVID-19 pandemicBiological sciences; Biotechnology; Diagnostics; Public health; Virology
