The Thyroid Function Panel provides a comprehensive overview of thyroid hormone production, conversion, and autoimmune activity. It includes T3 (Triiodothyronine), Reverse – RT3; Thyroid-Stimulating Hormone (TSH); T3 (Triiodothyronine), Total – T3; Free T3 (Triiodothyronine); T4 (Thyroxine), Total and Free – T4FT4; and Thyroid Autoantibodies Profile – TAB.
This panel evaluates how effectively the thyroid and pituitary glands are working together, how well T4 is being converted to active T3, and whether autoimmune activity may be affecting thyroid function. It is valuable for identifying hypothyroidism, hyperthyroidism, Hashimoto’s, Graves’ disease, or subclinical thyroid imbalances.
