Abstract
Abstract We assessed the ability of the BinaxNow rapid test to detect severe acute respiratory syndrome coronavirus 2 antigen from 4 individuals with Omicron and Delta infections. We performed serial dilutions of nasal swab samples, and specimens with concentrations of ≥100 000 copies/swab were positive, demonstrating that the BinaxNow test is able to detect the Omicron variant.
