The presence of mupirocin may interfere with the BinaxNOW COVID-19 Antigen Self Test and may cause false-negative results. Cycle threshold (Ct) values from real-time RT-PCR were compared using a Mann-Whitney U Test; 95% confidence intervals (CIs) were calculated using the exact binomial method. The faster turnaround time of the antigen test can help limit transmission by more rapidly identifying infectious persons for isolation, particularly when used as a component of serial testing strategies. 2 2021/08, COVID-19 All-In-One Test Kit User Manual - Optimized PDF COVID-19 All-In-One Test Kit User Manual - Original PDF, D1013515A QUICK START GUIDE Refer to the Product Information Leaflet for more complete information.
