TSH helps regulate the thyroid gland. It is produced by the pituitary gland in response to thyroid hormone levels in the bloodstream. A high level of TSH means not enough thyroid hormone production, and low TSH indicates too much thyroid activity.
Thyroxine (T4) is the main hormone produced by the thyroid. A Total T4 test measures the overall level of T4 output by the thyroid gland.
Free T4 affects tissue function in the body, while bound T4 does not. This test is often used in congunction with TSH testing to measure the extent of hyper- or hypothyroidism.
Up to 10% of the population in the U.S. has iodine deficiency. Iodine is essential in healthy thyroid hormone production, brain function, breast tissue, fetal development and more.
