TSH Blood Test

$37.50 $25.00
TSH is created by the pituitary gland, and that can be located at the base of the brain. The gland is used to regulate thyroid hormones. You can find the thyroid at the front of the neck and is butterfly shaped. The thyroid produces three main hormones - triiodothyronine (T3), thyroxine (T4) and calcitonin. Metabolism and growth are just some of the functions controlled by the thyroid. The thyroid gland and pituitary gland work together to make sure the right about of thyroid hormones are produced. When this system is disrupted it can play havoc on the body. A TSH can show how well the thyroid is working.
