mariPOC and qRT-PCR SARS-CoV-2 results (+ or −) with Ct values that were available for the sensitivity cohort 1. Comparator qRT-PCR was not done for the sample number 106 from unknown reason but was considered to have been positive as it would have been analysed because of antigen and confirmatory qRT-PCR positivity (Ct values for genes: E, 30.2; RdRP, 35.2; N, 35.78).
