Binax-CoV2 performance based on Cycle Threshold (Ct) cutoffs. A Bar graphs represent the sensitivity of the Binax-CoV2 assay at various Ct thresholds. Performance of the assay is optimized at Ct < 20, where sensitivity is > 95%. B Ct value of all patient samples from the community setting included in the Ct analysis, plotted in ascending order. Blue circles represent Binax-CoV2–positive samples; orange squares represent Binax-CoV2–negative samples. Asymptomatic patients are indicated by open symbols, and symptomatic patients are indicated by filled symbols
