Collection: Thyroid Testing

What Is Measured?

The small butterfly-shaped thyroid gland at the base of the neck produces important hormones, necessary for metabolism, growth, and development.  A healthy thyroid works to regulate a number of processes and functions including the breakdown of food for energy, heart rate, respiration, body temperature, weight, and cholesterol.

Thyroid tests measure the amount of T3 (Triiodothyronine) hormone and T4 (thyroxine) hormone released by the thyroid into the bloodstream. TSH (thyroid-stimulating hormone), which stimulates the thyroid to release T3 and T4, TPOAb thyroid autoantibodies and Tg thyroglobulin, may also be measured.
