A new study updates the state of knowledge about antigen rapid diagnostic tests (Ag-RDT) in the diagnosis of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
In a new study, researchers examined the analytical sensitivity of three widely used rapid antigen tests used in the USA to detect the SARS-CoV-2 Omicron variant, compared with the WA1 strain.
Researchers test commercially rapid antigen tests to evaluate their analytical sensitivity and specificity, as well as clinical sensitivity for detecting SARS-CoV-2.
