Screening is “the application of a test to detect a potential disease or condition in a person who has no known signs or symptoms of that condition at the time the test is done” . Screening with thyroid function tests can identify clinically inapparent subclinical thyroid dysfunction. Subclinical hypothyroidism is diagnosed when a patient has an elevated thyroid-stimulating hormone (TSH) level as determined by a sensitive TSH test and a normal thyroxine level. Subclinical hyperthyroidism is diagnosed when a patient has an undetectable TSH level and a normal thyroxine level. Screening also detects overt thyroid dysfunction, which is diagnosed when a patient has an elevated TSH level and a low thyroxine level (overt hypothyroidism) or an undetectable TSH level and an elevated thyroxine level (overt hyperthyroidism).
