We wanted to know whether commercially available, rapid point-of-care antigen tests are accurate enough to diagnose COVID-19 infection reliably, and to find out if accuracy differs in people with and without symptoms.
To assess the diagnostic accuracy of the rapid antigen test (RAT) compared with RT-PCR (reference standard) for SARS-CoV-2, we searched MEDLINE/PubMed and Web of Science for relevant records. The QUADAS-2 tool was used to assess study quality, and ...

13 lut 2024 · A Johns Hopkins Medicine-led study provides evidence that rapid antigen tests for COVID-19 administered at home (upper image) yield results as reliable as those performed by a medical professional (lower image).
The overall sensitivity of rapid antigen detection tests versus that of RT-PCR with oral, anterior nasal, and nasopharyngeal samples was 18.18% (95% confidence interval [CI] 8.19% to 32.71%), 63.04% (95% CI 47.55% to 76.79%), and 73.33% (95% CI 58.06% to 85.4%), respectively. All sampling methods had a test specificity of 100% regardless of the ...
4 gru 2020 · Are at-home rapid COVID-19 tests dependable? While we're leaning more into rapid antigen tests and the government's making them available, the accuracy of the tests hasn’t changed. They're more accurate in symptomatic people than asymptomatic people.
