TSH

Interested in testing your hormones? Consider starting with your thyroid.

Your thyroid is essential to your health and wellbeing. From how fast your heart beats to how quickly your body burns calories, your thyroid directly influences factors as subtle as your mood and as vital as your fertility.

This test measures thyroid stimulating hormone (TSH): a hormone that stimulates the thyroid to produce T4 (thyroxine) and T3 (triiodothyronine), two hormones that play a critical role in controlling the body’s metabolism. Typically, changes in your thyroid hormones can result in significant changes to your TSH level, indicating potential problems related to the function of your thyroid.
