A highly specific test should rule out all true negative results. The results confirm similar sensitivity of self-collected anterior nasal swabs to that of professionally collected nasopharyngeal swabs for patients with a CT of < 30 determined by RT-PCR. A test's sensitivity is also known as the true positive rate. The overall sensitivity of rapid antigen detection tests versus that of RT-PCR with oral, anterior nasal, and nasopharyngeal samples was 18.18% (95% confidence interval [CI] 8.19% to 32.71%), 63.04% (95% CI 47.55% to 76.79%), and 73.33% (95% CI 58.06% to 85.4%), respectively. Whats the difference between them? 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). Sensitivity and specificity mathematically describe the accuracy of a test which reports the presence or absence of a condition. Emergency Use Authorizations Looking at these three examples it seems that the test becomes more accurate as the overall probability of infection increases. 238 0 obj <>/Filter/FlateDecode/ID[<14C460633FC69F4E942E936439209C81>]/Index[194 73]/Info 193 0 R/Length 178/Prev 276921/Root 195 0 R/Size 267/Type/XRef/W[1 3 1]>>stream So in this case, when the proportion of the overall population who are infected is rather small, the test is swamped by false positives.
