21 kwi 2021 · Rapid antigen test (RAT) kits have emerged as an important alternative tool to aid in the clinical diagnosis of COVID-19. RAT is based on immunochromatography, which employs antibodies spotted onto nitrocellulose membranes that interact with specific antigens from the patient sample.
We included test accuracy studies of any design that evaluated commercially produced, rapid antigen tests. We included evaluations of single applications of a test (one test result reported per person) and evaluations of serial testing (repeated antigen testing over time).
4 lis 2021 · The sensitivity of different SARS-CoV-2 Ag RDT varied over a wide range. The sensitivity limit of 75% for panel members with Cq ≤ 25 was met by 96 of the 122 tests evaluated; 26 tests exhibited lower sensitivity, few of which failed completely. Some RDT exhibited high sensitivity, e.g. 97.5 % for Cq < 30.
Rapid antigen tests (RATs) offer results more rapidly (approximately 15–30 min), are easy to perform and do not require highly trained staff and specialized laboratory equipment. Rapid SARS-CoV-2 antigen detection reduces the turnaround time for obtaining the results, allowing the immediate isolation of the infected individuals.
11 gru 2023 · Self-testing is an effective tool to bridge the testing gap for several infectious diseases; however, its performance in detecting SARS-CoV-2 using antigen-detection rapid diagnostic tests...
To assess the diagnostic accuracy of the rapid antigen test (RAT) compared with RT-PCR (reference standard) for SARS-CoV-2, we searched MEDLINE/PubMed and Web of Science for relevant records. The QUADAS-2 tool was used to assess study quality, and ...
29 mar 2023 · Our aim was to determine the most sensitive and specific rapid test for the diagnosis of SARS-CoV-2. Design: Rapid review and diagnostic test accuracy network meta-analysis (DTA-NMA).
