TSH is the message your brain sends to tell the thyroid to make more hormone. It's a useful quick screen, but it doesn't show how well thyroid hormone is converted or whether antibodies are present — the Thyroid Panel Test gives the full picture.

What results can reveal

  • Whether your brain is pushing the thyroid harder than usual
  • Whether a full thyroid panel may be worthwhile

How we interpret it

We read every panel through a functional lens — optimal reference ranges, ratios, and cross-panel patterns. Results become part of your written Root Cause Report and your personalized 12-week protocol.

We read TSH alongside your HTMA calcium/potassium ratio, and if anything looks off we suggest the full Thyroid Panel Test to check conversion and antibodies.
