For health professionals  

The prevalence of hypothyroidism may be up to 10% of the general population, most frequently afflicting older women.1 More asymptomatic people may have subclinical disease that can be detected through thyroid function testing but the value of detecting subclinical disease is unclear. In the past decade, requests for thyroid function tests have increased by 51% (2001/02 to 2010/11), without evidence of a corresponding increase in prevalence. Thyroid function tests are not recommended to be requested routinely in asymptomatic low-risk people in Australia.2
