975-Item Intolerance Testing.

The number of people who believe they have a food intolerance has risen dramatically over recent years.

A food intolerance is difficulty digesting certain foods and/or having an unpleasant physical reaction to them. It causes symptoms, such as bloating and stomach pain, which usually come on a few hours after consuming the food. Many people assume they have a food intolerance when the true cause of their symptoms is something else. The 975-item hair intolerance test includes a wide range of food, non-food items, pollens and plants found in and around your home.

All we require at RT Aesthetics is a small sample of your hair. The expert lab technicians take your hair and analyse the sample in our lab so that we can discover what is causing your potential intolerance symptoms. The full list of items tested.

Intolerance Test

The testing facility completed tests on more than 400,000 samples received worldwide and has over 10 years of experience dedicated to helping people restore their body’s natural balance. Additionally, the Mars III (Multiple Analytical Resonance Systems) bioresonance equipment used at the facility for testing is manufactured and recognised as a medical scanning device class 11a according to ISO EN 13485.

Food intolerance or food allergy isn’t always anaphylaxis or a rash. It can be achy joints, the feeling of a flu setting in, or even nausea or a migraine. The test covers a wide range of items, such as dairy, wheat and eggs, plus fruits and vegetables. After your hair has been tested, you will receive an easy-to-understand report that lists all of the items that will cause a reaction. Also in the report is advice on how to change your diet to remove these items.

This test offers more coverage than our other tests, as well as an accurate analysis of the items you should avoid. By following the advice in your report, you will feel happier and healthier! Watch the video above to find out more about how quick, easy and effective food intolerance testing can be.

Our expert team of bioresonance technicians and lab managers have spent the last 13 years continually developing hair testing technology to bring you the most effective tests on the market, covering the largest number of trigger items, all from our ISO9001 accredited allergy and intolerance testing laboratory.

Our Care.


In general, people who have a food intolerance tend to experience the following although this is not a complete list and some people may experience different symptoms. These symptoms usually come on a few hours after eating the food. It can be difficult to know for sure whether you have a food intolerance as these are very general symptoms that are typical of many other conditions.

  • Tummy Pain
  • Bloating
  • Wind
  • Diarrhoea
  • Skin Rashes
  • Itching
Food Allergy.

A food allergy is where your body reacts to certain foods. It’s often mild, but can be very serious for some people.

  • Food allergy is a reaction from your immune system (your body’s defence against infection) – your immune system mistakenly treats proteins found in food as a threat
  • Food allergy can trigger typical allergy symptoms, such as a rash, wheezing and itching, after eating just a small amount of the food (these symptoms usually come on rapidly)
  • Food allergy is often to particular foods – common food allergies in adults are to fish and shellfish and nuts, and in children to milk and eggs as well as to peanuts, other nuts and fish
Food Intolerance.

A food intolerance is when you have difficulty digesting certain foods or ingredients in food. It’s not usually serious, but eating the food you’re intolerant to can make you feel unwell.

  • Food intolerance does not involve your immune system – there is no allergic reaction, and it is never life-threatening
  • Food intolerance causes symptoms that come on more slowly, often many hours after eating the problem food
  • Food intolerance only results in symptoms if you eat reasonable amounts of the food (unlike an allergy, where just traces can trigger a reaction)
