Your sample is analysed for IgG antibodies to a wide range of foods. You’ll receive a detailed digital report highlighting which foods may be contributing to symptoms such as bloating, fatigue, skin issues, or digestive discomfort.
You won’t be left to interpret your results alone. Once your report is ready, our support team can help you understand your findings and guide you on how to adjust your diet. We also offer optional nutritionist consultations for personalised advice on food elimination or reintroduction.
We dispatch your test kit within 1–2 working days. UK customers typically receive their kit within 2–3 business days. Return postage is prepaid for your convenience, and you can track your order through our support team at any time.
Our laboratory uses validated ELISA technology to test for IgG antibodies to over 200 common foods and ingredients. This method is widely used in clinical immunology for detecting immune responses. While results provide valuable guidance, food intolerance testing should be used alongside professional dietary advice for best results.

Why Some Foods Stall Results
Food intolerances can quietly slow your weight loss. When your body reacts to certain foods, it triggers inflammation, bloating, and hormonal imbalances that affect metabolism and water retention. Removing trigger foods like dairy, gluten, or soy helps reduce inflammation, improve digestion, and support steady fat loss.

A food intolerance blood test (also known as an IgG food test) measures your body’s immune response to different foods. It detects IgG antibodies in your blood, which can indicate that certain foods may be contributing to symptoms such as bloating, fatigue, headaches, skin irritation, or digestive discomfort.
The test involves taking a small blood sample, usually through a quick and painless finger prick. Your sample is analysed in a certified laboratory to identify foods that may be causing an intolerance response. The results provide a clear overview of which foods you may want to limit or eliminate.
A food allergy triggers an immediate immune reaction (IgE antibodies), which can be severe and even life-threatening. A food intolerance, on the other hand, causes a delayed reaction (IgG antibodies), often leading to more subtle symptoms that appear hours or even days later.
No fasting is required. However, it’s best to eat a normal, balanced diet in the days leading up to the test so that all foods you regularly consume are accurately represented in your results.
Results from your food intolerance blood test are usually available within 5–10 working days after your sample is received by the lab. You’ll receive a detailed report outlining your reactivity to a wide range of foods and ingredients.
Your report will group foods into categories such as dairy, grains, fruits, vegetables, meat, seafood, and nuts. Each food will be graded according to your antibody response, helping you understand which items to avoid or reduce.
Yes. Many people are able to reintroduce certain foods after following an elimination plan and giving their body time to reset. Reintroduction should be done gradually, ideally under the guidance of a nutritionist or healthcare professional.
No. This test identifies food intolerances only. It does not diagnose food allergies, coeliac disease, or other medical conditions. If you suspect these, consult your GP for appropriate testing.
Some medications, including steroids and immunosuppressants, may affect your antibody levels. If you take regular medication, check with your doctor before completing the test.
Yes, the food intolerance blood test is suitable for most children over 2 years old. For younger children or those with specific health concerns, please consult a healthcare professional first.
