About Thyroid Stimulating Hormone Test
Thyroid stimulating hormone (TSH) is produced by the pituitary gland to regulate the production of thyroid hormones thyroxine (T4) and triiodothyronine (T3). It is produced in response to levels of circulating hormones.
Raised levels of Thyroid Stimulating Hormone can indicate that the thyroid is struggling to produce sufficient quantities of thyroid hormones and is underactive, whereas low levels can indicate that the thyroid is producing excess levels of thyroid hormones and is overactive.
