Food Sensitivity Testing
Introductory Food Sensitivity IgG Test
Also known as: IgG food sensitivity screen (5 foods)
A simple first look at five of the most common food sensitivities.
An entry-level version of the full Food Sensitivity IgG Test. It checks IgG reactivity to five foods that are among the most common sensitivities, largely because they're eaten so often. A good first step when symptoms are mild, and a smaller, more manageable list of foods to work with.

- Gliadin (gluten)The protein in wheat, barley, and rye.
- Cow's milkDairy proteins.

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.
Any reactive foods are paused while we support the gut, then reintroduced — a simple way to see whether food is part of your picture.
