Advanced thyroid function

The thyroid is a gland found in the neck. It produces hormones that are released into the bloodstream to control the body's growth and metabolism. An overactive or underactive thyroid leads to hormone imbalances which can cause symptoms such as tiredness, weight gain and feeling depressed.

  • Thyroid Stimulating Hormone (TSH)
    Thyroid-stimulating hormone is a pituitary hormone that stimulates the thyroid gland to produce thyroxine, and then triiodothyronine which stimulates the metabolism of almost every tissue in the body.
  • Free Thyroxine (FT4)
    Thyroid hormones not bound to proteins. FT4 lowers when the thyroid is struggling.
  • Triiodothyronine (FT3)
    Triiodothyronine, also known as T3, is a thyroid hormone. It affects almost every physiological process in the body, including growth and development, metabolism, body temperature, and heart rate.
  • Thyroxine (T4)
    Total T4 levels offer a good index of thyroid function when the thyroid-binding globulin is normal and nonthyroidal illness is not present
  • Anti-Thyroidperoxidase antibodies (TPEX)
    Thyroid peroxidase (TPO) is an enzyme made in the thyroid gland that is important in the production of thyroid hormone. TPO is found in thyroid follicle cells where it converts the thyroid hormone T4 to T3.
  • Anti-Thyroglobulin antibodies (TGAB)
    Thyroglobulin autoantibodies bind thyroglobulin (Tg), a major thyroid-specific protein. Tg plays a crucial role in thyroid hormone synthesis, storage, and release.
