Test sensitivity indicates the ability of the test to correctly identify patients that have the disease. 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: RIDTs are not recommended for use in hospitalized patients with suspected .

Medical articles on testing. Essentially, a lower limit of detection indicates a more sensitive test, with fewer viral copies per sample necessary to elicit a positive test result. Background: 10.1128/JCM.00938-20 1735 0 obj <> endobj IMPORTANCE Rapid antigen detection devices for SARS-CoV-2 represent a valuable tool for monitoring the spread of infection. The ratio $p = P/N$ is the proportion of infected in the general population. Subject: qv otc consumer received false positive for 1st test; went to er room & reported pcr and antibody test as negative -- tss advised of qv otc sensitivity and specificity for positives and negatives; will log feedback for review and follow-up investigation conclusion: tested 5x retained devices with negative standard. A test's sensitivity is also known as the true positive rate. Test results were read after 15 min, and participants completed a questionnaire in the meantime.

They have been advocated for use by the World Health Organisation to help control outbreaks and break the chain of transmission of COVID-19 infections. So in this case, when the proportion of the overall population who are infected is rather small, the test is swamped by false positives. But there remain 950 people in the sample who are.
