Detailed Clinical Overview
TSH, or thyroid stimulating hormone, is produced by the pituitary gland and helps regulate the thyroid gland. The thyroid produces hormones that affect metabolism, body temperature, heart rate, energy levels, digestion and many other functions.
Because of the feedback loop between the pituitary and thyroid, TSH is commonly used as an initial laboratory test when assessing thyroid function. An elevated TSH may occur with an underactive thyroid, while a low TSH may occur with an overactive thyroid.
