About Our Thyroid Test Panel
Note: Fasting is not required for this test.
The Thyroid Panel is an important panel of tests that evaluating how the thyroid is functioning. It is also used to diagnose hyperthyroidism and hypothyroidism (having an over-active or under-active thyroid).
The thyroid is an endocrine gland that not only controls metabolism, but also secrete hormones that are necessary for growth, development and nearly every physiological process in the body. It is no wonder that you want to check up on yours when you feel imbalanced.
Our Thyroid Panel includes measuring the following three thyroid levels:
- T3 uptake (Triiodothyronine) - T3 is the active form of T4. This hormone informs cells to use digested food as energy, rather than store it as fat.
- T4 (Total Thyroxine) - A total T4 test measures the T4 that has bonded to protein and the free (unbonded) T4 in the blood.
- T7 (Free Thyroxine Index) - This measurement is a calculation of T4 and T3 uptake.
