Looking at these three examples it seems that the test becomes more accurate as the overall probability of infection increases. The fast-spreading Omicron variant has made us increasingly reliant on at-home rapid antigen tests to tell us whether we have Covid-19. 50]P]&Ljn00a@fb` 9!f 9 `H/`LlX}&UK&_| _`t@ Specificity of available antibody tests may vary by assay; it is important to check the validation data provided by the manufacturer and/or performing laboratory. For the QuickVue rapid test the sensitivity was 8.5% (4.8-13.7%, 95% CI) and specificity was 99.2% (95.6-100%, 95% CI). The nasopharyngeal tract likely has (1) active virus replication and (2) enough virus to be detected in test kits. Yet recent studies raise questions about the tests'. While the main advantage of rapid antigen detection tests is the immediate availability of results, PCR should be preferred in crucial settings wherever possible.
