There is often confusion between screening and diagnosis. This often
happens because the same tests can be used for both purposes. While
screening occurs in individuals who are asymptomatic, or not suspected
of having the disease in question, diagnosis is used to confirm whether
someone actually has a disease. For example, a blood sugar test in
someone that is healthy would be a screening test. The same test in
someone with symptoms of diabetes would be diagnostic. Most screening
tests, when used in healthy people, require follow-up testing for
diagnosis.
