Thyroid Panel Blood Test
Test subject must be 18 years or older.
Understand your thyroid health
An understanding of thyroid health is essential for those experiencing symptoms such as dry skin, weight gain, depression, anxiety, hair loss, sexual dysfunction, and fatigue.
Your thyroid gland sits in the lower portion of your neck and acts as the metabolic throttle for every cell in your body! When your thyroid doesn't function efficiently, it can affect every cell in your body.
Since undiagnosed thyroid problems can increase your risk of obesity, depression, anxiety, hair loss, sexual dysfunction, and fatigue, it's very important that you don't go undiagnosed.
- Thyroid-Stimulating Hormone (TSH) — Evaluates overall thyroid function.

- Free Tri-iodothyronine (T3) — Measures the amount of T3 (the active form of the hormone) available to the cells and tissues.
