New Brochure on Thyroid Function Tests

Format: Brochure
Institute: National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)

The thyroid is a small, butterfly-shaped gland located in the front of the neck below the larynx, or voice box. It makes two thyroid hormones, which circulate in the bloodstream and act on virtually every tissue and cell in the body, affecting metabolism, brain development, breathing, heart and nervous system functions, body temperature, weight, cholesterol levels, and more. Thyroid Function Tests, a new brochure from the National Endocrine and Metabolic Diseases Information Service, provides easy-to-understand information on what the thyroid gland does and the tests that are used to assess its function.
