Did you know that food allergies affect between 1-2% of the UK population, with some allergens resulting in hospital admissions? Up to two million people are living with a diagnosed food allergy, but the majority are not aware of their triggers. Getting a food intolerance test in the UK is a crucial step in knowing the food allergens that trigger adverse reactions in your body.

What is a Food Intolerance Test?

There are three types of food reactions. They might have similar reactions and symptoms on the surface, but they have essential physiological differences. 

  • Food sensitivity – This is when the body produces immunoglobin antibodies as part of an immune reaction when you eat something. It typically happens when large bits of food get into the bloodstream, commonly due to a leaky gut. In this case, the reactions are slow to appear, and a person could eat foods they are sensitive to and not experience any symptoms until a few days later. 
  • Food intolerance – This refers to reactions that arise from compromised digestion. This reaction doesn’t affect the immune system; the sensitivities and intolerances are not life-threatening. They can be easily confused without a correct diagnosis. 
  • Food allergy – Finally, food allergies trigger an immediate immune response when eaten, often requiring immediate medical attention. 

People can develop food intolerances or allergies due to genetics and the environment. In either case, knowing the foods that don’t agree with your body is crucial, and a food intolerance test is the first step. 

The food intolerance test looks at your blood chemistry to see which IgG proteins are present and provides insight into how your body responds to certain foods. The alternative is to try an elimination diet, which could take time and guesswork. With a food intolerance test, you will quickly have the results you need, which are highly accurate.

Why Might You Need a Food Intolerance Test?

Several factors might inform your decision to get a food intolerance test, such as; 

  • Family history of allergies or food intolerances 
  • Allergies such as hay fever and eczema 
  • Asthma 
  • Other food allergies 

The symptoms of food intolerance and allergies present differently for each individual. Some have skin reactions as the first system; in others, it’s the respiratory system, while others experience difficulties with their digestive system. If you notice any such negative reactions after eating certain types of food, it’s a good idea to get a test to identify the culprits to avoid them.

Benefits of Getting a Food Intolerance Test

Taking a food intolerance test has many benefits; 

  • It can help you better manage your diet if you know the foods you are sensitive to or allergic to
  • It can help differentiate between an allergy and an intolerance 
  • Can prevent future severe allergic reactions
  • Can help you lead a better everyday life by knowing the foods you should avoid for a trouble-free lifestyle 
  • It is the first step towards effective treatment 

A food intolerance test isn’t something you should take lightly, even though you haven’t experienced any adverse reactions yet. Taking the test can help identify a variety of undetected or not yet experienced food sensitivities that could lead to various problems such as weight gain, digestive disorders and migraines, among other conditions.

Types of Food Intolerance Tests

There are various types of food intolerance tests available; some are not scientifically backed but occasionally work with some luck. This test is an antibody-based test. 

  • Antibodybased tests – These are the most effective tests. The antibody–based tests evaluate your IgG antibody levels against foods available under various brand names. They also help to identify foods involved in IBS and migraine symptoms. The accuracy of these tests increases when combined with side-by-side duplicate testing. 

Other tests that are less used include muscle response tests, provocation and neutralisation tests and electro-dermal screening tests. These tests require more time for assessment, and they aren’t widely available. The standard and most commonly used food intolerance tests are antibody-based tests.

Food Intolerance Test FAQs

Q: How much is a food intolerance test in London?

The cost of a food intolerance test varies depending on where you get the test from and the methods and equipment used. There are home test kits available, but these have been proven to be extremely unreliable and inaccurate. You can contact us for a free quote on your food intolerance test and further details about the test.


Q: How do I get tested for food intolerance?

A food intolerance test can take various forms depending on the type of bloodwork performed. But the basic principle is that we draw blood and perform bloodwork to identify potential food sensitivities. You don’t have to worry about trying out many different food items. We simply mark and monitor various biomarkers to see their response towards different foods and compounds. As the blood reacts to the compounds, the results are measured and recorded, from which we draw conclusions.


Q: Are food intolerance tests accurate?

It depends on the type of food intolerance test in question. Medical experts agree that at-home food sensitivity tests are not reliable. However, IgE and IgG blood tests have proven more effective and accurate at identifying food sensitivities and intolerances.


Q: What are the 3 most common food intolerances?

The 3 most common food intolerances are lactose, which is found in milk, casein, which is also found in mild, and gluten in grains such as barley, rye and wheat.

This blood test includes the biomarkers shown below along with information about each biomarker.

What does the Food Intolerance Test London blood test involve?

This blood test is just like a standard blood test.

You will be asked to uncover you left or right arm and suitable vein is found. A tourniquet will be placed and tightened around your upper arm allowing the veins to swell and a needle will be placed into your vein. A small quantity of blood is then drawn into tubes. Once the procedure is complete a small plaster will be placed onto the site which can be removed after a few hours.

How do I prepare

  • The blood test requires access to the area of interest, therefore, it is recommended to wear loose clothing to facilitate this process.
  • No specific preparation is required for this test.

I've been to this clinic 4 times over the past 7 years for both pregnancy scans and health scans.... What sterling services they consistently provide! Booking is always easy either online or over the phone, minimum waiting time, and calming environment. What's most impressive is that Mr Usman always explained the scan results thoroughly in a calm and professional way on site and in a report, and quickly spotted issues that both my hospital scan and community clinic scan completely missed (the sonographer at the hospital even asked where I did my scan as she was impressed)! This helped me eventually get timely referral and free from lots of stress. I always feel being well looked after by the team and will wholehearted recommend them to anyone who is looking for efficient, caring and professional more
