The thyroid is a butterfly-shaped endocrine gland in the neck that makes two thyroid hormones: thyroxine (T4) and triiodothyronine (T3). These hormones are carried to every part of the body, where they are used for energy, warmth, and organ function. If the thyroid begins to overproduce or underproduce hormones, this is called hyperthyroidism or hypothyroidism, respectively. A thyroid panel contains a number of tests listed below that help to measure the hormone levels for the detection of these conditions.
The thyroid-stimulating hormone (TSH) is a good warning system, as the test detects TSH changes before the hormone levels change too drastically. A high TSH can indicate hypothyroidism, while a low TSH indicates hyperthyroidism.
Thyroxine (T4) is the main form of thyroid hormone in the blood and contains 4 iodine atoms. However, when the body needs it, one of the atoms is lost during the conversion into triiodothyronine (T3), its active form. The T3 tests help diagnose hyperthyroidism and its severity when the levels are high. The T3 total test measures both free T3 and bound T3, which are the amount of available T3 not attached to anything and the amount of T3 attached to protein, respectively. These tests help monitor treatment for thyroid disease.
