The thyroid gland, a small butterfly-shaped gland located at the front of the neck, is one of the most important endocrine glands in the body. It oversees the regulation of numerous vital processes, such as metabolism, energy production rate, growth, and development. The thyroid gland produces two essential hormones, T3 (triiodothyronine) and T4 (thyroxine), while the thyroid-stimulating hormone (TSH) regulates their production. A thyroid function panel aids in the accurate assessment of this vital gland's functions and the early detection of any disorders that may affect it.
