370-Item Food Sensitivity Panel: Is It Worth Getting?

Written by Kristy Beard, MSN, APRN, FNP-C — Board-Certified Family Nurse Practitioner and Founder of Elevate Health and Wellness, serving patients across the Gulf Coast in Gautier, MS and Foley, AL.

What Does a 370-Item Food Sensitivity Panel Test?

A 370-item food sensitivity panel — also called a comprehensive IgG food sensitivity panel — measures your immune system's IgG antibody response to 370 different foods, spices, additives, and environmental substances. IgG antibodies are produced by the immune system as part of a delayed hypersensitivity response — meaning reactions can appear hours to days after consuming a trigger food, making them extremely difficult to identify through observation alone.

Foods typically included in a comprehensive panel span all major food categories: grains and gluten-containing grains, dairy products, eggs, meats and fish, fruits, vegetables, legumes, nuts and seeds, oils, sweeteners, spices and herbs, food additives and colorings, and common environmental allergens. The result is a detailed reactivity map showing which foods are producing elevated IgG responses in your immune system at the time of testing.

The Case For Comprehensive Food Sensitivity Testing

The clinical argument for comprehensive food sensitivity testing rests on the relationship between IgG-mediated immune activation, intestinal permeability, and systemic inflammation. Research published in the journal Gut suggests that elevated IgG responses to specific foods are associated with increased intestinal permeability — sometimes called 'leaky gut' — and that eliminating high-reactivity foods can reduce systemic inflammatory burden. For patients with chronic inflammatory conditions, digestive symptoms, skin disorders, headaches, joint pain, or fatigue that has not responded to conventional treatment, this information can be genuinely transformative.

The Limitations to Understand

IgG food sensitivity testing is not without controversy. The presence of IgG antibodies to a food may indicate immune exposure rather than pathological sensitivity in some cases. Test results can vary over time and are influenced by recent dietary patterns. False positives are possible. For these reasons, at Elevate Health and Wellness, Kristy Beard, MSN, APRN, FNP-C interprets food sensitivity panel results in the context of your complete clinical picture — not as a standalone diagnosis. The panel is a starting point for a structured elimination and reintroduction protocol, not a prescription for permanent avoidance of every flagged food.

How Elevate Uses Food Sensitivity Results

When a patient at Elevate completes a comprehensive food sensitivity panel, Kristy reviews the results alongside their symptom history, inflammatory markers, and gut health indicators. She designs a targeted elimination protocol focusing on the highest-reactivity foods, monitors symptom response, and guides a systematic reintroduction process to identify which eliminations produce meaningful clinical benefit. This structured approach transforms a list of lab results into an actionable, personalized dietary strategy.
