Food Intolerance Test
This is a results-only service. You will receive your lab report to review yourself — no consultation or interpretation is included.
Food & Drink Intolerance Testing (IgG Panel)
This test analyses your blood for IgG-mediated immune responses to 200 food and drink ingredients. It uses a simple finger-prick blood sample collected at home. No venous blood draw is required.
Results are sent directly to you.
What the test measures
- Reactivity (IgG antibody levels) to 200 ingredients, including common foods, drinks, and potential dietary triggers.
- Results are presented in an easy-to-read “traffic light” format: high reactivity, borderline/reactive or normal, giving you a clear overview of possible intolerances.
When you might consider this test
- If you frequently experience digestive issues, bloating, IBS-like symptoms, skin conditions, headaches, fatigue or other chronic symptoms that may be linked to diet.
- When you want a starting point for a personalised elimination diet to identify foods your body might be reacting to and reduce immune or digestive burden.
Important notes
This test is not the same as a food allergy test (IgE), nor does it detect enzyme deficiencies (e.g. lactose intolerance), coeliac disease, or chemical/histamine sensitivities.
This test measures IgG antibodies, which are part of the immune system. Pregnancy and breastfeeding can affect IgG levels, sometimes suppressing or altering immune responses.
Because of this, results may be less accurate during these times. If possible, testing is best carried out once pregnancy or breastfeeding has completed, so that results truly reflect your baseline immune activity.
For the test to detect a reaction, the immune system must have been exposed to that food. Foods that haven’t been eaten for several weeks may not show up, simply because IgG levels decline when exposure stops. For the most accurate results, continue eating your usual diet in the weeks leading up to testing unless you have a known allergy or medical reason to avoid certain foods.
Blood analysis carried out in a laboratory is the only reliable and scientifically validated method for assessing food intolerances.
Hair testing is not accurate for identifying immune-mediated food reactions, as hair does not contain circulating antibodies or immune markers. If you have previously used a hair-based food intolerance test, please be aware that those results may not reflect true physiological reactions, and this IgG blood test provides a far more accurate picture.
