Sensitivity and specificity - Wikipedia In children with symptoms, diagnostic sensitivity and specificity were 71.8% and 98.7%, respectively, and in those without symptoms, sensitivity and specificity were 56.2% and 98.6%, respectively. Often called "rapid tests" or "home COVID tests," these rapid antigen tests rely on a. General Information - Coronavirus (COVID-19) Of these, 95% = 180 will test positive. endstream endobj 1773 0 obj <>/Metadata 142 0 R/Outlines 202 0 R/Pages 1768 0 R/StructTreeRoot 258 0 R/Type/Catalog>> endobj 1774 0 obj <>/ExtGState<>/Font<>/XObject<>>>/Rotate 0/StructParents 0/Tabs/S/Type/Page>> endobj 1775 0 obj <>stream Please use the form below to provide feedback related to the content on this product.

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. While the main advantage of rapid antigen detection tests is the immediate availability of results, PCR should be preferred in crucial settings wherever possible. endstream endobj 108 0 obj <.
