the public’s awareness of respiratory diagnostics was one of the pandemic’s most surprising impacts. The terms “PCR” and “antigen test” have become commonplace in day-to-day conversations, with many likely having taken at least one of these...
PCR tests, the gold standard for SARS-CoV-2 testing, provide high accuracy and therefore high confidence in the test results. Antigen tests are convenient when only a few results are needed, which may be advantageous in the point-of-care setting. Cont...
rapid antigen testThe aim was to determine the accuracy of anterior nasal swab in rapid antigen (Ag) tests in a low SARS-CoV-2 prevalence and massive screened community. Individuals, aged 18years or older, who self-booked an appointment for real-time reverse transcriptase-polymerase chain ...
PCR tests use a technique called reverse transcription polymerase chain reaction (RT-PCR) to detect the virus’s genetic material. The test sample is usually saliva or a swab taken from your nose or throat. “An at-home PCR test has a higher degree of accuracy than an antigen test,” say...

Rapid antigen (RA) tests are being increasingly employed to detect SARS-CoV-2 infections in quarantine and surveillance. Prior research has focused on RT-PCR testing, a single RA test, or generic diagnostic characteristics of RA tests in assessing testin

Therefore, these studies were considered to have an unclear risk of bias on the reference test. No other domain had a high risk of bias or a high applicability concern (Fig. 2). Diagnostic accuracy of hRT-PCR assay When all 18 studies using the hRT-PCR assay were eval- uated together,...
The accurate quantification of antigens at low concentrations over a wide dynamic range is needed for identifying biomarkers associated with disease and detecting protein interactions in high-throughput microarrays used in proteomics. Here we report the
