Food Sensitivity Testing : IgG-Mediated Immune Response

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. This test is often included in functional medicine tests, integrated medicine testing, and root cause testing protocols at leading functional health centres and longevity labs in Delhi / India.

Functional medicine practitioners in Delhi/India may recommend this test alongside holistic health tests, preventive longevity tests, or biological age test programs to provide a comprehensive understanding of diet-related inflammation and overall wellness.

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. Integration with functional medicine diagnostics, functional medicine tests, and integrated medicine testing allows functional health centres or longevity labs in Delhi / India to provide tailored treatment programs, complementing longevity tests and biological age test assessments.

What the Food Sensitivity 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

This test supports holistic health tests, root cause testing, and functional medicine diagnostics, allowing functional medicine practitioners in Delhi/India to make precise dietary recommendations that optimize gut health and overall wellness.

How the Food Sensitivity Test Works

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

Clinical Benefits of Food Sensitivity Testing

• 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
• Complements functional medicine tests, holistic health tests, longevity tests, and biological age test programs at functional health centres or longevity labs in Delhi / India

Sample Requirement

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