While PCR-tests are usually considered as the gold standard to detect infection with the SARS-CoV-2 coronavirus in terms of sensitivity as well as specificity, antigen tests (Ag-Tests) offer practical advantages in terms of costs, logistics and speed [].Because Ag-Tests may play a major role in large scale testing strategies [2, 3] in populations with low prevalence, besides . Testing among symptomatic participants indicated the following for the BinaxNOW antigen test (with real-time RT-PCR as the standard): sensitivity, 64.2%; specificity, 100%; PPV, 100%; and NPV, 91.2% ( Table 2 ); among asymptomatic persons, sensitivity was 35.8%; specificity, 99.8%; PPV, 91.7%; and NPV, 96.9%. 2021;23(4):407416. Patriquin G, LeBlanc JJ, Williams C, Hatchette TF, Ross J, Barrett L, Davidson R. Microbiol Spectr. The terms sensitivity and specificity may not appear in the manufacturers information sheets, but are often reported as positive percent agreement and negative percent agreement. Sensitivity may also be measured by calculating the limit of detection, which is the lowest detectable number of virus copies in a sample at which the test will return a positive result at least 95% of the time. Therefore, with these values of sensitivity and specificity, a nominal 48 will be found to be infected, and $850 + 2$ uninfected. %%EOF Please sign in to view account pricing and product availability.
