Quidel QuickVue Test The company says positive results with the Quidel QuickVue test agree with PCR tests 83.5% of the time and that negative results agree 99.2% of the time. The QuickVue At-Home OTC COVID-19 Test is a lateral flow immunoassay, with results readable by eye. In addition, there will be 800 who are not infected, and 5% or about 40 of these will test as positive, making a total of 220. Effectiveness of isolation, testing, contact tracing and physical distancing on reducing transmission of SARS-CoV-2 in different settings. Test sensitivity indicates the ability of the test to correctly identify patients that have the disease. Antigen tests are designed to detect proteins from the virus that causes COVID-19, in anterior nasal swabs. Overall sensitivity and specificity of AT tests were respectively 63.5% (95% confidence interval (CI): 49.0 - 76.4) and 100% . 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. %PDF-1.6 % Background: Often called "rapid tests" or "home COVID tests," these rapid antigen tests rely on a. Developed with RADx support by San Diego-based diagnostic company Quidel, this test is easily performed with a nasal swab and offers results in just 10 minutes.

For diagnostic tests, it is the ability to identify those samples which are not infected with SARS-CoV-2. Selection of the outpatient cohort. That also means that the remainder of the $N-P$ uninfected people, or $(1-b)(N-P)$, will test positive (these are the false positives). Current status of the lateral flow immunoassay for the detection of SARS-CoV-2 in nasopharyngeal swabs. So in this case, when the proportion of the overall population who are infected is rather small, the test is swamped by false positives.
