WebSpecificity = 97.2% In other words, the company’s blood test identified 97.2% of those WITHOUT Disease X. A specific test is used for ruling in a disease, as it rarely misclassifies those WITHOUT a disease as being sick. A perfectly specific test therefore means no healthy individuals are identified as diseased. Additional measures WebA test with high sensitivity will correctly identify most people who have the condition, and a test with high specificity will correctly identify most people who don’t have the disease.
