So in this case, when the proportion of the overall population who are infected is rather small, the test is swamped by false positives. SARS-CoV-2 infection status was confirmed by RT-PCR. The QuickVue At-Home COVID-19 Test is a type of test called an antigen test. ; The results for the company's Sofia SARS Antigen FIA, which in May was the first such diagnostic to receive FDA emergency use authorization, are in line with the sensitivity rates of polymerase chain reaction (PCR) tests.

In general, ARTs can achieve a sensitivity of about 80 per cent for cases with higher viral loads and a specificity range of 97 to 100 per cent, said HSA. In the sample of 1000, there will be around 50 who are currently infected. PMC 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.
