IgG Food Antibodies (87 IgG foods + Total IgE)

Available through our international laboratory collaboration with Genova Diagnostics

Overview

Food sensitivities are delayed immune reactions that may contribute to a wide range of chronic symptoms, including digestive issues, headaches, fatigue, skin conditions, and mood disturbances. Unlike food allergies, which involve an immediate IgE-mediated response, food sensitivities are typically IgG-mediated and can take hours or even days to appear, making them harder to identify without testing.

The Food Sensitivity Test evaluates IgG antibody responses to a broad panel of common foods, helping to uncover hidden triggers and guide dietary interventions.

Why Test for Food Sensitivities?

Unidentified food sensitivities can contribute to:

• Bloating, gas, and abdominal discomfort
• Diarrhea or constipation
• Headaches and migraines
• Chronic fatigue and brain fog
• Joint pain and inflammation
• Skin conditions such as eczema or acne
• Mood swings, anxiety, or depression

By identifying problem foods, patients and clinicians can develop a personalized nutrition plan that reduces inflammation, restores gut health, and improves overall well-being.

What the Test Measures

• IgG antibody levels to a wide range of common foods (panel size depends on the test chosen).
• Highlights reactive foods and their severity.
• Provides a detailed, patient-friendly report to guide elimination diets and reintroduction strategies.

How the Test Works

1. Sample Collection – A simple blood draw (serum sample).
2. Laboratory Analysis – Advanced immunoassay methods measure IgG reactivity against specific food proteins.
3. Results Report – Foods are categorized based on reactivity (high, moderate, low), with guidance for dietary modification.

Clinical Benefits

• Identifies hidden food triggers contributing to chronic health issues.
• Provides a roadmap for elimination diets without guesswork.
• Helps reduce systemic inflammation and support gut health.
• May improve symptoms in conditions such as IBS, migraine, autoimmune disorders, and chronic fatigue.

Sample Requirement

• Specimen Type: Serum (blood sample)
• Collected at home (via finger stick) or clinic (venipuncture), depending on the kit provided.
