If individuals who have the condition are considered "positive" and those who don't are considered "negative", then sensitivity is a measure of how well a test can identify true positives and specificity is a measure of how well a test can identify true negatives: Shafie MH, Antony Dass M, Ahmad Shaberi HS, Zafarina Z. Beni Suef Univ J Basic Appl Sci. J Mol Diagn. Sensitivity measures how often a test correctly generates a positive result for the condition being tested.

Understanding the false negative rates of SARS-CoV-2 RT-PCR testing is pivotal for the management of the COVID-19 pandemic and it has implications for patient management. For diseases that are primarily respiratory in nature, like COVID-19, nasopharyngeal swabs have been the most reliable, as they sample an area of the respiratory tract where the virus appears to first infect an individual. doi: 10.1128/spectrum.02455-21.

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 . That also means that the remainder of the $N-P$ uninfected people, or $(1-b)(N-P)$, will test positive (these are the false positives). 2023 Feb 3:acsinfecdis.2c00472.

Conclusions: The clinical sensitivity of SARS-CoV-2 RT-PCR testing was only moderate at best. Because they detect molecules that are specific to SARS-CoV-2, the specificity of nucleic acid tests for COVID-19 is very high, meaning that a positive result can generally be trusted. Accessibility 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. Noninclusion in this list should not be interpreted as a judgment on the validity or legitimacy of tests.
