Food intolerance test

A food intolerance blood test is designed to identify sensitivities caused by certain foods by measuring the body's natural IgG (immunoglobulin G) response when those foods are consumed.

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. If IgG levels become elevated when exposed to specific foods, this suggests a stronger immune response or intolerance to those foods.

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.

Our food intolerance test measures dairy specific IgG antibody reactions across foods such as cow's milk, goat milk, and sheep's milk. Our test does not specifically measure lactase (the enzyme that breaks down lactose), instead it can identify a dairy intolerance.

A gut microbiome health test kit can help to identify a lactose intolerance and will provide more comprehensive insights into how your diet and lifestyle may be influencing your overall health.

Our test will show if you have an intolerance to many gluten containing grains including barley, wheat, rye, malt, oat, durum wheat, gliadin, spelt, couscous and wheat bran.

The test will also identify whether gluten containing grains are the cause of your symptoms or whether they are caused by another food type.

We offer 2 options, the standard food intolerance test priced at ?250 or our comprehensive food intolerance test that measures 270 different types of foods for ?300.

You will receive your results in 2-5 working days once our lab has received your blood sample.

Once you have identified the foods that trigger your symptoms and removed them from your diet, your symptoms can improve quickly if you are no longer coming into contact with the foods that triggered your symptoms. However everyone responds differently, for others it may take days, weeks or months.

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.
