Question Solved1 Answer The specificity of a diagnostic test is the probability that an individual does not have the disease being tested for when they have tested negative. Suppose that a COVID-19 test is given to 100 people, 26 of which have the disease and 74 of which do not. Of those who have the disease, 23 test positive and 3 test negative; of the 74 who do not have the The specificity of a diagnostic test is the probability that an individual does not have the disease being tested for when they have tested negative.
