Differentiate between sensitivity and specificity, using an example to illustrate the differences
Sensitivity is the proportion of subjects with the disease or condition who have a positive test result. A sensitive test rarely misses people with the disease or condition, and it is often used in screening situations to detect a disease or condition in people who appear to be asymptomatic. Specificity is the proportion of subjects without the disease or condition who have a negative test. Specific tests are used to confirm a diagnosis. The oral glucose test is a highly specific test for diagnosing diabetes mellitus, whereas a blood draw to check cholesterol is more sensitive.
