Food intolerance test

A food intolerance blood test measures your IgG (immunoglobulin G)
antibody response to individual foods. Where a food shows an elevated
result, that may indicate a food sensitivity to it.

IgG is the most common antibody found in the blood; antibodies are natural proteins that are produced by your immune system that protect you when an unwanted substance enters your body.

The test requires a blood sample to be taken which is then exposed to a panel of specific foods in our lab, we expose your blood to over 270 different types of food.

Where IgG levels are elevated for a specific food, that may indicate a food sensitivity to it. Food sensitivity here means a food-specific IgG antibody reaction. It is not the same thing as a food allergy, coeliac disease or lactose intolerance, and this test does not diagnose any of those.

Your results will include your reactivity levels to all 270+ foods that we test for. All foods are grouped into normal, borderline and elevated reactivity levels so you can easily identify your problem foods.

You will receive both a digital and printable version of your results.

Not quite, our panel measures your IgG response to dairy foods individually, including the specific milk proteins (casein, alpha-lactalbumin, beta-lactoglobulin), across cow, goat, sheep, buffalo and camel milk.

An elevated result may indicate a sensitivity to those milk proteins, which is different from a lactose intolerance.

It can tell you whether dairy protein, rather than milk sugar, is worth looking at.

The panel measures your IgG response to gluten-containing grains individually: wheat, gliadin, wheat bran, durum wheat, spelt, barley, rye, malt and couscous.

An elevated result may indicate a sensitivity to that grain, and because each grain is measured separately, your report can show whether a response sits with wheat specifically or across
grains.

This test cannot diagnose coeliac disease. If gluten regularly makes you unwell, ask your GP about coeliac
testing before cutting gluten out, because you need to still be eating it for that NHS test to work.

We offer two options: the Food Intolerance Test covering 130 foods (£150), and the Complete Food Intolerance Test covering 270 foods (£170). Both include the finger-prick kit, pre-paid return postage, full lab analysis of all four IgG subtypes, your report, and nutritionist support.

You will receive your results in 5 working days once our lab has received your blood sample.

Everyone responds differently. Some people notice a difference within days of adjusting the foods their results flagged; for others it takes weeks, and sometimes a flagged food turns out not to be the issue at all.

The way to know is to make changes one at a time, in a structured way with our team's guidance, and let your own symptoms be the judge.

No, nutrition during pregnancy is more important than ever, we do not recommend making any major adjustments to diet and lifestyle during this time. It is also common for food intolerances to arise during pregnancy and cause symptoms such as acid reflux.

To take the test you need to live in the UK. This is because our labs are based in the UK and need to receive your blood sample as fast as possible.

We will send you a finger-prick collection kit to take your blood sample. The kit will include everything you need to take the test. Simply prick your finger, collect your blood, and send it back to our lab on the same day using the pre-paid return shipping label.

Step-by-step instructions will also be included in your test kit.

We recommend taking your blood sample in the morning and sending it back to us on the same day.

No, you do not need to fast before you take the test.

You can buy a test online from a number of providers. We recommend ensuring that the test is a blood test and is analysed by an ISO accredited lab within the UK.

This test can be used by anyone over the age of 2 years old. However, for children, we would recommend our gut microbiome test which is a more comprehensive test and comes with a full nutrition and supplement plan developed by our team.
