Figure 1

Concordance of BinaxNOW rapid antigen test results with positive rRT-PCR results over 6 testing rounds among staff at a horse racetrack, California, USA, November–December 2020. All rRT-PCR–negative results (n = 642) were concordant with BinaxNOW results, so only rRT-PCR–positive results (n = 127) are shown. Crossbars represent mean Ct for the concordant and discordant pair groups in each testing period. The dashed line represents Ct = 30. Ct, cycle threshold; rRT-PCR, real-time reverse transcription PCR.
