For health professionals  

While it is appropriate to test people if there is clinical suspicion of thyroid function disorder, or if symptoms or risk factors are present, there is a lack of convincing evidence that early treatment of subclinical disease will improve quality of life in otherwise healthy patients.1-3. In a person who is thought to have a thyroid dysfunction, testing assists diagnosis and enables appropriate management before complications develop. In the past decade, requests for thyroid function tests have increased by 51% (2001/02 to 2010/11), but the prevalence of thyroid dysfunction has not increased.

Find out more about when a thyroid function test may be warranted and why it should not be performed in the absence of symptoms.
