Ag-RDTs have a good specificity varying from 93.2 to 100% depending on the kits in comparison with RT-PCR.In our study, the specificity of the BIOSENSOR test was 100% and the sensitivity was 47.17%.This drop of the specificity is explained by the decrease of the viral load with the ...
Previous research on SARS-CoV-2 infection has determined optimal timing for testing in quarantine and the utility of different frequencies of testing for infection surveillance using RT-PCR and generalized rapid antigen tests. However, these strategies can depend on the specific rapid antigen test used...
RT-PCR = reverse transcriptase polymerase chain reaction; Ag-RDT = antigen rapid diagnostic testing; LTCF = long-term care facility. Full size image Cost-effectiveness of surveillance interventions varied by orders of magnitude across LTCFs (Fig. 4). In LTCF 1, assuming baseline per-test unit ...
Since autumn 2020, rapid antigen tests (RATs) have been implemented in several countries as an important pillar of the national testing strategy to rapidly
The QuickNavi-Ebola™ showed a sensitivity of 56.8% (95% CI 53.6–60.0) and a specificity of 97.5% (95% CI 96.2–98.4), the OraQuick® Ebola Rapid Antigen test displayed 61.6% (95% CI 57.0–65.9) sensitivity and 98.1% (95% CI 96.2–99.1) specificity, the Coris® EBOLA Ag K-...
(6) Automated SARS-CoV-2 antigen tests In Germany, due to the early and strong promotion of PCR diagnostics along- side the introduction of RATs, there was no significant gap in demand between these two diagnostic tools that could have been filled by automated antigen tests. Although these ...

We looked for studies that measured the accuracy of any commercially produced, rapid antigen or molecular point‐of‐care test, in people tested for COVID‐19 using RT‐PCR. People could be tested in hospital or the community. Studies could test people with or without symptoms. Tests had to...
A public health test for detecting someone who might be contagious is, by logical deduction, expected to have a sensitivity of around 30–40% versus PCR when testing a random sample of asymptomatic people in a steady-state outbreak.18 Furthermore, the asymmetry of RNA reflecting more infectious...
