In this chapter, the routine application of thyroid function tests for hypothyroidism detection is evaluated, with a focus on the problems of overdiagnosis and unnecessary treatment, especially in subclinical scenarios. It critically assesses the lack of solid evidence behind common interventions, like the widespread prescription of levothyroxine without definitive clinical need. Highlighting evidence-based guidelines for hypothyroidism screening, the chapter argues against indiscriminate thyroid testing. It advocates for a thoughtful approach to thyroid disorder management, urging cautious use of TSH tests to reduce needless medical actions and improve patient outcomes.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
