Test accuracy of rapid diagnostic tests and reverse‐transcription polymerase chain reaction against virus isolation in cell culture for assessing SARS‐CoV‐2 infectivity: Systematic review and meta‐analysis

open access: yesReviews in Medical Virology, Volume 34, Issue 4, July 2024.
Abstract We aimed to assess the performance of Ag‐RDT and RT‐qPCR with regard to detecting infectious SARS‐CoV‐2 in cell cultures, as their diagnostic test accuracy (DTA) compared to virus isolation remains largely unknown. We searched three databases up to 15 December 2021 for DTA studies. The bivariate model was used to synthesise the estimates. Risk
