Premium Food & Drink 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.

Testing for IgG antibodies to specific foods can help identify potential food intolerances that may be contributing to chronic symptoms such as bloating, fatigue, skin issues, and digestive discomfort. Clinical studies and real-world evidence have shown that making dietary changes based on IgG antibody levels can lead to noticeable improvements in health and wellbeing.

Many individuals have experienced significant relief from symptoms after adjusting their diets to reduce or eliminate foods that trigger an IgG response, making this test a valuable tool in personalised nutrition and long-term health management.

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.
