Sensitivity measures how often a test correctly generates a positive result for the condition being tested. So in this case, when the proportion of the overall population who are infected is rather small, the test is swamped by false positives. 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. 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.
