Difference between presumptive test and confirmation test

Explanation:

A presumption test or screening is a test to detect diseases in early stages and shows the prevalence of a disease in the population, it is performed in asymptomatic people, which is classified as having or not having the disease that is sought, the objective of these tests are to reduce morbidity-mortality in the study population, confirmatory tests or diagnostic tests are those that confirm or rule out the disease and are performed after a screening test, an example is HIV-AIDS tests, in which the screening test is performed on the population with risky sexual contacts called the rapid test, ELISA and if it is positive, the Western Blot confirmation test is performed.
