Real-life clinical sensitivity of SARS-CoV-2 RT-PCR test in - PubMed PCR; SARS-CoV-2; infectious disease; rapid antigen detection; sensitivity; specificity; swabbing; test performance. Among 871 paired specimens from asymptomatic participants, 21 (2.4%) were antigen-positive and 17 (2.0%) were real-time RT-PCR-positive. Of these, the fraction who are infected, which we can interpret as the probability that a given person who tests positive is actually one of the infected is $$ { aP \over aP + (1 - b)(N-P) } $$, We can express this formula in terms of probabilities instead of population sizes.
