What's included in this test?
TSH
Thyroid stimulating hormone (TSH) is a hormone produced by the pituitary gland that regulates the production of thyroid hormones thyroxine (T4) and triiodothyronine (T3) by the thyroid gland. TSH levels increase when thyroid hormone levels are low, and decrease when thyroid hormone levels are high. Abnormal TSH levels can indicate problems with the thyroid gland, such as under or overproduction of thyroid hormones. It can also be a result of pituitary gland disorders.
Free thyroxine
Thyroxine (T4) is one of the two primary hormones produced by the thyroid gland. It plays a vital role in regulating metabolic processes in the body. T4 is mostly bound to carrier proteins in the blood, and only a small amount of it exists in its free or unbound form. In contrast to free T3, free T4 is relatively inactive, but it is still essential for normal body function. When the body requires thyroid hormone, free T4 is converted to the more active form, free T3.
