The Food & Drink Reactivity Test combines both IgE Allergy Testing and IgG Intolerance Testing to provide a comprehensive understanding of your body’s response to different foods and drinks.

Why test for both allergies and intolerances?

  • IgE Allergy Testing detects immediate immune responses to specific foods, which can result in symptoms like rashes, swelling, difficulty breathing, or digestive issues. These reactions typically occur within minutes or hours of consumption and may require medical attention.

  • IgG Intolerance Testing identifies delayed immune responses to foods, which can take hours or even days to appear. Intolerances are often associated with chronic or recurring symptoms such as bloating, headaches, fatigue, or joint pain.


By testing for both, this dual analysis provides a complete picture of your food reactivity, helping you identify not just severe allergies but also subtler intolerances that may impact your day-to-day well-being.

Common symptoms that may overlap

  • Digestive Issues: Bloating, constipation, diarrhoea, or stomach cramps.
  • Skin Reactions: Rashes, eczema, or hives.
  • Fatigue: Persistent tiredness or lack of energy.
  • Respiratory Problems: Sneezing, nasal congestion, or shortness of breath.
  • Headaches or Migraines: Recurring or unexplained.
  • Joint or Muscle Pain: Chronic aches without an obvious cause.

This mix of allergy and intolerance testing empowers you with knowledge about what your body thrives on and what it struggles with, helping you achieve optimal health.

  • Easy to follow instructions
  • Free return envelope to our Lab

Clinical Testing

Food & Drink Reactivity Test - IgE Blood Test

What it is A laboratory blood test using a small finger-prick sample, measuring IgE antibodies — the specific antibody class produced during a true allergic reaction.
What it looks at Your immune system's antibody response to specific allergens. A raised IgE level to a particular allergen indicates your immune system has been sensitised to it.
Best for
  • Investigating a suspected allergy, particularly fast-onset reactions
  • Supporting a wider medical assessment alongside your GP or allergist
  • Anyone who wants testing grounded in clinically recognised methodology

If you suspect a serious or rapid-onset allergy, this test should sit alongside — not instead of — professional medical advice. Antihistamines, steroids or immunosuppressants may affect results; speak to your doctor before testing if you're taking any of these.

IgE (Immunoglobulin E) allergy testing is a clinically recognised method used to assess immune responses associated with allergic reactions.

By measuring allergen-specific IgE antibodies in the blood, testing can help identify potential food and environmental allergens that may be contributing to symptoms.

“Many people experiencing allergy-related symptoms know something feels ‘off’, but identifying what may be contributing to those reactions is not always straightforward.”

“Over the years, I’ve seen how frustrating it can be when symptoms continue without clear answers. Allergy testing can help provide greater clarity by looking at how the immune system may be responding to common food and environmental allergens.”

“Having a clearer understanding of potential triggers can help people feel more informed, more confident, and better supported in deciding their next steps.”
