WebSpecificity Specificity is the ability of a test to identify patients that do not have the disorder in question. [9] In other words, specificity is the proportion of the population without the target disorder who test negative for the disorder i.e D/ (B+D). [7] Therefore, tests that are highly specific are useful for ruling in a disorder. WebSpecificity is the Ratio of true negatives to total negatives in the data. Specificity is the correctly -ve labeled by the program to all who are healthy in reality. Specificity = TN / (TN + FP) Numerator: -ve labeled healthy worker.
