This advanced panel typically includes:
- TSH (Thyroid-Stimulating Hormone)
- Free T4 (Thyroxine)
- Free T3 (Triiodothyronine)
- Reverse T3
- Thyroid Peroxidase Antibodies (TPO Ab)
- Thyroglobulin Antibodies (Tg Ab)
Together, these markers evaluate thyroid production, hormone conversion, and autoimmune activity.
Many thyroid symptoms are missed with basic testing alone. Extended testing helps:
- Detect autoimmune thyroid disease
- Identify poor T4-to-T3 conversion
- Explain persistent symptoms with “normal” TSH
- Support precise medication and dosing decisions
- Establish a detailed baseline for long-term monitoring
This level of insight allows for more personalized and effective treatment strategies.
