| Popis: | The Abbott BinaxNOW rapid antigen test is cheaper and faster than real-time reverse transcription PCR (rRT-PCR) for detecting severe acute respiratory syndrome coronavirus 2. We compared BinaxNOW with rRT-PCR in 769 paired specimens from 342 persons during a coronavirus disease outbreak among horse racetrack workers in California, USA. We found positive percent agreement was 43.3% (95% CI 34.6%–52.4%), negative percent agreement 100% (95% CI 99.4%–100%), positive predictive value 100% (95% CI 93.5%–100%), and negative predictive value 89.9% (95% CI 87.5%–92.0%). Among 127 rRT-PCR–positive specimens, the 55 with paired BinaxNOW-positive results had a lower mean cycle threshold than the 72 with paired BinaxNOW-negative results (17.8 vs. 28.5; p |
