Thyroid Panel with TSH
The Thyroid Panel with TSH includes:
Free thyroxine (T4) index; total thyroxine (T4); Triiodothyronine (T3) uptake (THBR); TSH
Your thyroid regulates your body’s metabolism. It functions like a thermostat to control body temperature.
Thyroid Stimulating Hormone (TSH) stimulates the thyroid gland to secrete the hormones Thyroxine (T4) and Triiodothyronine (T3). Triiodothyronine (T3) exhibits greater activity and is produced in smaller quantity. It is the most powerful thyroid hormone, and affects almost every process in the body, including body temperature, growth, and heart rate. Thyroxine (T4) is the major thyroid hormone.
