The sensitivity of a test is defined as the proportion of cases with a specific disease or condition that give a positive test result.Sensitivity represents how much of a given substance is measured; the more sensitive the test,the smaller the amount of assayed substance that is measured.The specificity of a test is defined as the proportion of cases with absence of the specific disease or condition that gives a negative test result.In comparison,the prevalence of a disease is the proportion of a population that has the disease.This is in contrast to the incidence of a disease,which is the number of subjects found to have the disease within a defined time period,such as a year,in a population of 100,000.A positive predictive value for a test indicates the number of patients with an abnormal test result who have the disease,compared with all patients with an abnormal result.A negative predictive value for a test indicates the number of patients with a normal test result who do not have the disease,compared with all patients with a normal (negative)result.
