Sensitivity and specificity mathematically describe the accuracy of a test which reports the presence or absence of a condition. The relatively high false negative rates of SARS-CoV-2 RT-PCR testing need to be accounted for in clinical decision making, epidemiological interpretations, and when using RT-PCR as a reference for other tests. National Library of Medicine The objective of our study was to evaluate the sensitivity and specificity of rapid antigen detection tests versus those of reverse transcriptase PCR (RT-PCR) using oral, anterior nasal, and nasopharyngeal swabs.

Antigens are found on the surface of the virus particle, which are also shed in patient tissues. Test sensitivity indicates the ability of the test to correctly identify patients that have the disease. The fastest test being used to diagnose people infected with the coronavirus appears to be the least accurate test now in common use, according to new research obtained by NPR.
