ABSTRACT Introduction The rapid antigen detection tests (RADTs) for SARS-CoV-2 infection could contribute to the clinical and public health strategies for managing COVID-19. This umbrella review aimed to explore the accuracy and sensitivity of RADTs for SARS-CoV-2 by assessing the incidence of false positivity associated with them. Areas covered Meta-analyses and systematic reviews on the sensitivity and specificity of commercially available RADTs with data on false-positive results were identified by searching the PubMed, EMBASE, Cochrane Library, and Web of Science databases from inception to 31 March 2022. All meta-analyses and systematic reviews on the sensitivity and specificity of rapid antigen tests were included. Data on the author and year, included studies, index tests, sample size, false negatives, false positives, and study quality based on AMSTAR 2 (Assessing the Methodological Quality of Systematic Reviews) rating were extracted from the included meta-analyses and systematic reviews. Expert opinion The false positivity rates in the included studies ranged from 0.0% – 4.0%. This study summarizes the available evidence on the incidence of false positivity in RADTs and shows it is less than 4.0%. Therefore, our findings imply that RADTs can be an appropriate, economic, and rapid detection method for mass screening of COVID-19.
