"Measuring the sensitivity of tests in asymptomatic people is an urgent priority," says Woloshin. "A negative result on even a highly sensitive test cannot rule out infection if the pretest probability—an estimate before testing of a person's chance of being infected—is high, so clinicians s...
that's very likely accurate. They are more likely than PCR tests to produce a false negative result—meaning that you get a negative test result but actually have the virus. Antigen tests were designed to confirm the presence of COVID-19 in highly infectious...

They make the perfectly sensible recommendation that"Any diagnostic test result should be interpreted in the context of the pretest probability of disease. For COVID-19, the pretest probability assessment includes symptoms, previous medical history of COVID-19 or presence of antibodies, any potential...
