A thyroid panel is a group of tests that may be ordered to evaluate thyroid gland function and to help diagnose thyroid disorders. The tests included in a thyroid panel measure the level of thyroid hormones in the blood.
Your thyroid gland is located in your neck, just below your Adam’s apple. The thyroid creates hormones and controls how your body uses energy and your body’s sensitivity to other hormones.
- Total T4: measures the T4 that's bonded to protein along with any free T4.
- T3 Uptake: is a blood test performed as part of an evaluation of thyroid function
- T3 Free : is used to assess thyroid function. It is ordered primarily to help diagnose hyperthyroidism and may be ordered to help monitor treatment of a person with a known thyroid disorder.
- T3 Total: This test measures the level of triiodothyronine (T3) in your blood. T3 is one of two major hormones made by your thyroid.
- TSH w/Reflex Free T4: For differential diagnosis of primary, secondary, and tertiary hypothyroidism. Also useful in screening for hyperthyroidism. This assay allows adjustment of exogenous thyroxine dosage in hypothyroid patients and in patients on suppressive thyroxine therapy for thyroid neoplasia.
- T4 Free: is used to find out how well your thyroid gland is working.)
- Thyroid peroxidase (TPO) : is an enzyme that plays an important role in making thyroid hormones.
Hyperthyroidism (overactive thyroid) occurs when your thyroid gland produces too much of the hormone thyroxine. Hyperthyroidism can accelerate your body's metabolism, causing unintentional weight loss and a rapid or irregular heartbeat. Several treatments are available for hyperthyroidism.
Hyperthyroidism is the production of too much thyroxine hormone. It can increase metabolism.
