TT3 is the main hormone that thyroid hormone does to various target organs. The serum TT3 concentration reflects the thyroid gland’s ability to function better than the thyroid gland. TT3 is an important indicator of early hyperthyroidism and the monitoring of recurrent hyperthyroidism and pseudo thyrotoxicosis.
