How Reliable Are Covid-19 Rapid Tests for Detecting Omicron? Lancet 2020. For diseases that are primarily respiratory in nature, like COVID-19, nasopharyngeal swabs have been the most reliable, as they sample an area of the respiratory tract where the virus appears to first infect an individual. Noninclusion in this list should not be interpreted as a judgment on the validity or legitimacy of tests. The .gov means its official. Healthcare professionals can purchase the QuickVue SARS Antigen Test through select authorized distributors. Overall sensitivity and specificity of AT tests were respectively 63.5% (95% confidence interval (CI): 49.0 - 76.4) and 100% . These tests require samples from the patient that are likely to contain virus. They have been advocated for use by the World Health Organisation to help control outbreaks and break the chain of transmission of COVID-19 infections. Quidel Corporation Disease 2019 QuickVue At-Home COVID-19 Test March 1 In children with symptoms, diagnostic sensitivity and specificity were 71.8% and 98.7%, respectively, and in those without symptoms, sensitivity and specificity were 56.2% and 98.6%, respectively. If a diagnostic test correctly identified 100% of all positive results, it would be as sensitive as possible.
