Rapid tests can help you stay safe in the Delta outbreak. %%EOF Antigen tests are designed to detect proteins from the virus that causes COVID-19, in anterior nasal swabs. A systematic review of the accuracy of covid-19 tests reported false negative rates of between 2% and 29% (equating to sensitivity of 71-98%), based on negative RT-PCR tests which were positive on repeat testing. Of these, the fraction who are infected, which we can interpret as the probability that a given person who tests positive is actually one of the infected is $$ { aP \over aP + (1 - b)(N-P) } $$, We can express this formula in terms of probabilities instead of population sizes. Federal government websites often end in .gov or .mil. Rapid antigen detection tests using self-collected anterior nasal swabs proved to be as sensitive as and more tolerable than professionally collected nasopharyngeal swabs for CT values up to 30 determined by RT-PCR. How accurate are rapid antigen tests for diagnosing COVID-19? Essentially, a lower limit of detection indicates a more sensitive test, with fewer viral copies per sample necessary to elicit a positive test result. 145 0 obj <>/Filter/FlateDecode/ID[<7B25B64DC0023C44A3787FE5A23F64CA>]/Index[107 67]/Info 106 0 R/Length 158/Prev 133259/Root 108 0 R/Size 174/Type/XRef/W[1 3 1]>>stream This work was supported by Academy of Finland (ELKE, grant no 308913) and Doctoral Programme in Biomedicine, Faculty of Medicine, University of Helsinki (SJ).
