Food Intolerance Tests

Hand with supplementsMany people suffer from food intolerance but do not realise that easy screening tests are available.

NB : These tests are available in the UK only. They cannot be taken:

  • If you are pregnant
  • By a child under two years old
  • If you are on steroidal medication.

In order to ensure test accuracy tested foods should have been part of the diet within the six weeks prior to doing the test.

Testing for Intolerances

There are many ways of testing for intolerance, from using machines in a clinic or health food store, using muscle testing (kinesiology), to using a blood test.

During the many years I have been in practice, I have steered away from the former two methods of food intolerance testing.

I have found over and over again, that to ensure absolute reliability, I could only recommend to my clients, the ELISA method of blood tests to help identify food intolerances, carried out by highly reputable laboratories. I use Lorisian, a part of YorkTest for professional use.

Does what you eat affect your health?

What happens if you are suffering adverse reactions to the foods you are eating?

Food intolerance is a major contributor to many health problems – it is estimated that over 45% of the population have a food intolerance and most don’t even know it.

Food intolerance is different from a classic Food Allergy (such as a peanut allergy) in that classic allergies can kill you, if you have even a modicum of the food.

The effect of a classic food allergy is instantaneous. The effect of a food intolerance can be hard to know, as it can affect you minutes after you eat to 24 hours after you eat. If you are eating the food or foods on a regular basis, you could even feel constantly unwell, without ever tracing it to the food you are eating.

So, if you are intolerant to foods, you can eat them daily, with no apparent and immediate effect on the way you feel. However, food intolerance can contribute to making you feel quite unwell with conditions such as: acne, migraines or headaches, depression, bloating, fluid retention, joint problems, eczema, sinusitis, sneezing, excess mucus, digestive problems and lack of energy. Food intolerance testing can help identify if the foods you are eating are causing you a health problem.

What the tests do?

If you are intolerant to foods, your immune system produces IgG (Immunoglobulin G) antibodies against that food. ( If you have a classic food allergy, like a peanut, strawberry or environmental allergy, your body will produce different antibodies called IgE (Immunoglobulin E) antibodies to the food or irritant.

The Laboratory I use has over 30 years experience in testing and identifying food intolerances. It provides a specialist personal health laboratory testing service and is committed to quality and the pursuit of Clinical Evidence. The laboratory uses a method called ELISA to detect circulating antibodies. This technique has been shown to be high reliable (95% to 97% reproducible ) in detecting a variety of antibodies using antigens of clinical importance.

Using just a small pin-prick of blood that can be taken easily, and a mailing kit, the test accurately identifies delayed adverse IgG mediated reactions to foods.

Then, when these foods are avoided for a period of time, it leads to a more stable immune response which contributes to improved health.

How many foods can I test for?

How do I take a Food Tolerance test?

The test is done in the comfort of your own home. I send you a kit which you use to take a tiny pin-prick sample of blood which you then mail directly to the laboratory with your details.

I will normally send your results and report back to you within 14 working days of you sending your sample to the laboratory.

What will I receive?

When you take a food intolerance test, I will send you your result which lists foods to avoid, foods you should eat only occasionally and foods you can eat freely, as appropriate. A free 10 minute follow-up telephone consultation is included in the price, to answer any queries you may have about your results.
