That makes another 48, and a total of 93 positive test results. The fast-spreading Omicron variant has made us increasingly reliant on at-home rapid antigen tests to tell us whether we have Covid-19. Rapid antigen detection tests using self-collected anterior nasal swabs proved to be as sensitive as and more tolerable than professionally collected nasopharyngeal swabs for CT values up to 30 determined by RT-PCR. We present sensitivity and specificity with 95% confidence intervals (CIs) for each test, and pooled data using the bivariate model. Sensitivity refers to the test's.

A diagnostic accuracy study comparing RNA LAMP, direct LAMP, and rapid antigen testing from nasopharyngeal swabs. These tests require samples from the patient that are likely to contain virus. The underlying prospective, diagnostic case-control-type accuracy study included 87 hospitalized and nonhospitalized participants in a positive and a negative sample cohort between 16 March and 14 May 2021 in two hospitals in Vienna. Antigen and Molecular Tests for COVID-19 The diagnostic testing field for COVID-19 is rapidly evolving, with many tests focused on diagnosing patients with active viral infections.
