Validation of an At-Home Direct Antigen Rapid Test for COVID-19 In addition, there will be 800 who are not infected, and 5% or about 40 of these will test as positive, making a total of 220. In general, ARTs can achieve a sensitivity of about 80 per cent for cases with higher viral loads and a specificity range of 97 to 100 per cent, said HSA. 2021. Specificity is the ability of the test to identify those the true negatives. The https:// ensures that you are connecting to the 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. government site.
