The QuickVue SARS Antigen Test is authorized for use on anterior nares (NS) swab specimens directly from . While the main advantage of rapid antigen detection tests is the immediate availability of results, PCR should be preferred in crucial settings wherever possible. Keywords: 6 The use of repeat RT-PCR testing as gold standard is likely to underestimate the true rate of false negatives, as not all patients in f The QuickVue At-Home COVID-19 Test is a type of test called an antigen test.

NAATs include thepolymerase chain reaction (PCR) assay in a laboratory to amplify viral genomic material for detection and can provide results in hours to days; other techniques include LAMP and next generation sequencing. Epub 2023 Feb 8. Among 307 symptomatic persons, sensitivity and specificity were 72.1% and 98.7%, respectively. 10.1016/j.jmoldx.2021.01.005 That makes another 48, and a total of 93 positive test results. April 29,;20(10):11511160. Yet recent studies raise questions about the tests'. Therefore, with these values of sensitivity and specificity, a nominal 48 will be found to be infected, and $850 + 2$ uninfected. ShelfLife : At least 9 months from date of manufacture. Quidel Corporation Headquarters: This test is authorized for non-prescription, unobserved, home use by . The ratio $q = (N-P)/N$ is the proportion of uninfected.
