Thyroid Function Panel

The Comprehensive Thyroid Function Panel provides an in-depth evaluation of thyroid hormone production, conversion, and autoimmune activity. This panel goes beyond basic TSH testing to deliver a complete picture of thyroid health.

Thyroid hormones regulate metabolism, energy levels, body temperature, mood, weight, and overall endocrine balance.

This panel includes:

• Thyroid-Stimulating Hormone (TSH) – Primary regulator of thyroid activity
• T4 (Thyroxine), Total & Free – Measures overall production and available hormone
• T3 (Triiodothyronine), Total – Assesses circulating active thyroid hormone
• Free T3 – Measures biologically active T3
• Reverse T3 (rT3) – Evaluates hormone conversion patterns
• Thyroid Autoantibodies Profile (TPOAb & TGAb) – Screens for autoimmune thyroid disease

This panel helps assess:

• Hypothyroidism and hyperthyroidism
• Persistent fatigue or low energy
• Weight fluctuations
• Brain fog or mood changes
• Impaired T4 to T3 conversion
• Hashimoto’s thyroiditis
• Autoimmune thyroid dysfunction

Why a Comprehensive Panel Matters

TSH alone does not always reveal conversion issues or autoimmune activity. By measuring hormone production, free hormone availability, conversion efficiency, and antibodies, this panel provides a more complete evaluation of thyroid function.
