The 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 reaction (RT-PCR) ...
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 ...
Stool antigen testing is subject to the same limitations as the urea breath test, with the added need to refrigerate or freeze stool specimens that cannot be tested immediately. For initial diagnosis, it is comparable in accuracy to the urea breath test. It is less accurate when used to ...
