Thyroid
4 markers in this category
Free T3 (Triiodothyronine)
Free T3 (triiodothronine) is considered the most active thyroid hormone. It may play a key role in regulating metabolism, energy production, and body temperature.
Free T4 (Thyroxine)
Free T4 (thyroxine) is the main hormone produced by the thyroid gland. It may serve as a precursor that your body converts into the more active T3.
TPO Antibodies
TPO antibodies target the thyroid peroxidase enzyme involved in thyroid hormone production. Elevated levels may indicate autoimmune thyroid conditions such as Hashimoto's thyroiditis.
TSH (Thyroid Stimulating Hormone)
TSH is thyroid-stimulating hormone. The pituitary gland makes it, and uses it to drive your thyroid.
