In order to evaluate the diagnostic accuracy of a new rapid test for COVID-19, results of the screening test were compared to the Reference golden standard (PCR test) in 20,000 individuals. From 1200 individuals who tested negative by the rapid test, only 800 were confirmed -ve. From 18800 individuals who tested positive by the rapid test, 17600 were confirmed COVID-19 positive. If the prevalence of COVID-19 is equal to 65%, then the probability of a individual with a positive rapid test to be PCR positive is: 97.1% 86.7% 75.2% 65.1%
