Advanced food intolerance screening using IgG4 antibody testing to identify delayed food sensitivities and optimize dietary choices.
Allergy and food sensitivity testing measures your immune system's response to specific substances. IgE-mediated allergy tests detect true allergies — immediate immune reactions that can cause hives, swelling, breathing difficulty, or anaphylaxis. IgG food sensitivity tests measure delayed immune responses that may contribute to chronic symptoms like bloating, fatigue, headaches, or skin issues hours to days after eating trigger foods. While IgE allergy testing is well-established in clinical medicine, IgG food sensitivity testing is a growing area that many functional and integrative practitioners use as a guide for elimination diets. These tests can help identify triggers that are difficult to pinpoint through observation alone.
Key Details
Who Is This For?
People experiencing unexplained digestive issues, skin problems, or chronic fatigue that may be food-related. Anyone with known allergies who wants comprehensive mapping of their triggers. Parents investigating potential food sensitivities in children. People considering an elimination diet and wanting data to guide which foods to remove.
What's Included
Preparation Required
No fasting required. Continue eating your normal diet for at least 2–4 weeks before testing — avoiding suspected trigger foods can cause false negatives. Inform the clinic of any antihistamines or immunosuppressants you're taking, as these can affect results.
