  • What’s the difference between a food allergy and intolerance?

    Allergy involves IgE‑mediated immune responses and can be life-threatening; intolerance is dose‑dependent, digestive and generally non‑life-threatening and may involve other immune pathways.

  • Can you have high IgG levels without symptoms?

    Yes, it's possible to have elevated IgG levels to certain foods and still feel perfectly fine. In some cases, the immune system is highly effective at clearing IgG-antigen complexes before they trigger any noticeable symptoms. This means that while the body is reacting to a food at the immune level, it may not lead to inflammation or discomfort - at least not immediately or consistently.

    That’s why IgG results are best interpreted alongside your personal health history, symptoms, and in consultation with a qualified practitioner.

  • Why do some foods trigger an IgG immune response?

    During normal digestion, food is broken down into smaller components like amino acids and fatty acids, which are safely absorbed into the bloodstream. However, if the gut lining becomes more permeable than usual — a condition sometimes referred to as "leaky gut" — larger fragments of undigested or partially digested food can enter the bloodstream.

    When this happens, the immune system may mistakenly identify these food particles as potential threats and produce IgG antibodies in response. This can lead to inflammation and a range of symptoms linked to food intolerances.

  • What are common symptoms of allergies vs intolerances?

    Allergies can include hives, swelling, breathing difficulty, vomiting, or anaphylaxis. Intolerances cause bloating, diarrhea, nausea, gas and abdominal pain.

  • How do elimination diets work?

    By removing potential trigger foods for 2–4 weeks, then reintroducing them one-by-one to identify causes of symptoms.

  • What does the report include, and can I get support after my test?

    All our reports include a full breakdown by item, displaying a simple colour-coded reactivity ratings, detailed insights, and free support from registered nutritionists.

    Our IgG and IgE functional medicine tests include a 1-2-1 virtual consultation with a full qualified Nutritionist so you can discuss your personalised results in more detail.

  • How much does a test cost, and how long does it take to get the results?

    Prices range from £26–£39.99 for sensitivity tests and £139–£179.99 for allergy (IgE) or intolerance (IgG) tests. Results are delivered within 3–5 days.
