Thyroid stimulating hormone (TSH)

Thyroid stimulating hormone (TSH)

Thyroid stimulating hormone (TSH) is one of the most important hormones currently used to diagnose thyroid abnormalities. This glycoprotein is secreted by the pituitary and stimulates release of thyroxine (T4) and triiodothyronine (T3) from the thyroid gland. TSH release from the pituitary is controlled by thyrotropin releasing hormone (TRH) stimulation and negative feedback from free T3 and free T4. In general, TSH appears to be the more sensitive indicator of thyroid hormone status.
