IgE allergy testing for common food and environmental allergens. Includes consultation with results.
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.

- 20–200+ substances (varies by panel)
- Fasting Required
- No
- Sample Type
- Blood draw

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.
Panel Categories
Biomarkers Tested
9Indicates immunity against HBV due to vaccination or previous infection.
Detects antibodies to hepatitis C virus, indicating current or past infection. A positive result requires confirmatory RNA testing. Hepatitis C is now curable with direct-acting antiviral medications in most patients.
Immunoglobulin E (IgE) is a protein associated with allergic reactions that is normally found in very small amounts in the blood. IgE functions as part of the body's immune system (its defence against 'intruders').
Immunoglobulin G (IgG) is the most common type of antibody in the blood, important for fighting bacterial and viral infections.
Imbalances in gut pH influence short-chain fatty acid production and their effects.
