Children's Food Intolerance Test

Our food intolerance test uses a lab technique called ELISA to detect IgG antibodies linked to food sensitivities. It checks your blood for immune responses against up to 286 different food antigens, helping to identify foods your body may not be tolerating well. After collecting a small blood sample - either through a finger prick or Tasso+ autodraw device - the sample is analysed using a specialised lab instrument. This device measures your IgG antibody levels with precision and provides a detailed report showing which foods may be triggering unwanted symptoms.

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.

Your blood test results include your reactivity ratings to the items analysed in your chosen test. Our test results are comprehensive but simple to follow and explain in full what everything means to make sure you fully understand it.

Once we’ve received your sample at our laboratory, you’ll receive your test results via email in just 3 working days.

You don’t need any medical knowledge or training to read our test results, as everything is laid out to make them quick and easy to understand.

As soon as our lab has received your blood sample we will send you an email to let you know your sample has arrived safely. If you haven’t received email correspondence from Check My Body Health, please check your email spam or junk folder in case our emails have gone into these folders.

Testing for IgG antibodies to foods can provide valuable insights into how your body may be reacting to the things you eat and drink on a regular basis. Unlike food allergies, which trigger an immediate immune response through IgE antibodies, food intolerances are often linked to IgG antibodies and can cause delayed symptoms that are harder to trace back to specific foods. Common reasons to test for IgG antibodies include: • Unexplained symptoms such as bloating, fatigue, headaches, joint pain, skin problems, or digestive discomfort. • Identifying hidden triggers - reactions may appear hours or days after eating, making it difficult to spot patterns without testing. • Personalised diet guidance - IgG testing helps highlight potential foods contributing to inflammation or discomfort, supporting more informed dietary changes. • Improved well-being - many people report higher energy, clearer skin, and better weight management after adjusting their diet based on IgG test results. It’s important to note that IgG testing is not used to diagnose food allergies or medical conditions. Instead, it can be a helpful tool for creating a tailored nutrition plan and supporting your overall wellness journey.

IgG stands for Immunoglobulin G - one of the main types of antibodies produced by your immune system. Antibodies like IgG play a key role in your body’s defence system, helping to identify and neutralise foreign substances such as bacteria, viruses, or even certain food components. There are several types of immunoglobulins, including IgA, IgE, IgG, and IgM, each with its own function. IgG is particularly important in identifying delayed immune responses, which are often linked to food intolerances rather than immediate allergic reactions.

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.

Whilst we allow blood allergy and intolerance testing from the age of 2 and above, there is evidence to show that allergies are not fully developed until the age of 7. Our advice would be to check with a medical professional before purchasing.
