Your thyroid is a small, butterfly-shaped gland that sits just below your larynx and produces the vital hormones triiodothyronine (T3) and thyroxine (T4). Every cell in the body depends on these thyroid hormones for metabolism regulation. If these hormones drop too low, the pituitary gland will produce additional Thyroid Stimulating Hormone (TSH) to stimulate hormone production. If you have concerns about your energy level, metabolism or overall wellbeing, it is critical to evaluate the balance of these intricately connected hormones with this comprehensive thyroid panel test.
