Elite Thyroid Profile — Comprehensive Thyroid Function Testing (T4, Tgbn, fT4, fT3, TPO & TSH)
The Elite Thyroid Profile is a comprehensive thyroid function blood test that goes beyond standard TSH testing to provide a complete picture of thyroid health. This advanced panel measures T4, thyroglobulin antibodies (Tgbn), free T4 (fT4), free T3 (fT3), thyroid peroxidase antibodies (TPO), and TSH — giving you and your practitioner an in-depth understanding of thyroid function, conversion efficiency, and autoimmune status.
What's Measured

TSH — thyroid-stimulating hormone, the standard thyroid marker
Free T4 (fT4) — inactive thyroid hormone ready for conversion
Free T3 (fT3) — active thyroid hormone that drives metabolism and energy
T4 (total) — total thyroxine level
TPO Antibodies — detects Hashimoto's thyroiditis autoimmune activity
Thyroglobulin Antibodies (Tgbn) — additional autoimmune marker for thyroid health

Who Needs the Elite Thyroid Profile?
This panel is ideal for individuals with suspected or known thyroid dysfunction, Hashimoto's thyroiditis, unexplained fatigue, weight changes, cold intolerance, hair loss, brain fog, or depression. It is also valuable for monitoring thyroid health during natural treatment protocols. Results reviewed by Michelle Tonkin ND with personalized recommendations.
Frequently Asked Questions
Q: Why measure both TPO and Thyroglobulin antibodies?
A: Some Hashimoto's patients test negative for TPO but positive for thyroglobulin antibodies. Testing both ensures more accurate autoimmune thyroid disease detection.
Q: What does low fT3 with normal TSH mean?
A: This pattern (sometimes called "low T3 syndrome") suggests poor T4-to-T3 conversion — a common issue that standard TSH-only testing would miss. The Elite panel catches this.
Q: How do I prepare for this test?
A: Detailed preparation instructions are included with your test kit. Generally, morning collection before taking any thyroid medications is recommended.
