Thyroid Function Testing in Ambulatory Practice

  • Angela M. Leung
  • Alan P. Farwell
Part of the Thyroid Function Testing book series (ENDO, volume 28)


Thyroid function tests are commonly obtained by both primary care physicians and various specialists in ambulatory practice for both the evaluation of symptomatic and screening assessment of asymptomatic thyroid disease. Abnormalities of thyroid function testing, including those which may not be clinically apparent, are common in the general population. Epidemiological studies have identified hypothyroidism (subclinical and overt) in 4.6–9.5% and hyperthyroidism (subclinical and overt) in 1.3–2.2% of individuals [1], while the incidence of mild/subclinical dysfunction in certain populations is much more common [2–4].
