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 clear what's out of balance, temporarily remove reactive foods, and rebuild the gut so minerals and nutrients absorb properly.
