THYROID PROFILE (TOTAL T3, TOTAL T4, TSH) A Thyroid Profile test, which includes Total T3 (Triiodothyronine), Total T4 (Thyroxine), and TSH (Thyroid Stimulating Hormone), is an essential diagnostic tool to assess the function of the thyroid gland. The thyroid is a butterfly-shaped gland located in the neck, and it plays a critical role in regulating metabolism, energy levels, growth, and development. The hormones T3 and T4 produced by the thyroid regulate various body functions, while TSH is produced by the pituitary gland to stimulate the thyroid to produce T3 and T4.
