Food Sensitivity Panel (IgG)
What This Test Measures
IgG antibody reactions to common foods
Conventional vs. Functional Optimal Range
The gap between these ranges is why you feel terrible with "normal" labs. Conventional medicine waits for disease. Functional medicine optimizes for health.
Gabriel's Take
An IgG panel does not diagnose a food allergy or sensitivity on its own: IgG to a food often reflects eating it (AAAAI). Gabriel uses a panel as a starting map for an elimination and reintroduction trial, read alongside gut health, symptoms and a food diary. How you feel when a food comes back is the answer that counts. Commonly flagged: gluten, dairy, eggs, soy, corn. Allergy symptoms go to an IgE test or an allergist.

When This Test Is High
IgG to a food often reflects eating it; with gut symptoms, reactive foods are candidates for an elimination trial, not a diagnosis
When This Test Is Low
Few or no IgG reactions to the foods tested
Related Conditions
Food sensitivities, IBS, autoimmune disease, eczema
Recommended Follow-Up
Use reactive foods as a starting list: remove a few for a few weeks, support gut health, then add them back one at a time and watch symptoms. Suspected allergy (hives, swelling, trouble breathing) needs an IgE test or an allergist
