Food Intolerance Test Kits

Many people suffer for years with painful symptoms caused by a food intolerance. Yet the challenge is in establishing precisely what the food is that is causing the problem. By taking a simple home test you can get to the root of the problem, quickly and painlessly. 

Why Use A Food Intolerance Test?

You may have had uncomfortable symptoms for a while after eating including constipation, bloating or diarrhoea but have never got to the cause of what is causing the reaction. It is often very difficult to pinpoint a food that may be upsetting you or even distinguishing between what is a mild food allergy and what is a food intolerance. Unless the food allergy is severe then mild allergies and intolerance can be hard to separate. Taking a general food intolerance test will help you to drill down on any food that is causing the problem. Another reason to carry out a home test is that food intolerance testing is not always available on the NHS.

Who Should Use A Food Intolerance Test?

If you have ever experienced a severe reaction to a food which has affected your ability to breathe then we would advise that you seek medical advice immediately. This is because you may have a serious food allergy which could be life threatening. But you may be one of the thousands of people who put up with irritating symptoms every day, these may include bloating, acid reflux, acne, irritable bowel syndrome, indigestion or just feeling uncomfortable after you have eaten. If this is you then you may be suffering from a food intolerance. A simple home test will help to whittle down  the offending food so that you can eliminate it from your diet.

What’s In A Food Intolerance Test?

Test providers can differ, but many will ask you for a sample of your hair. This will usually be 9-10 strands of hair. Using hair dye does not affect the result. Other test providers may ask you for a blood sample which you take using a lancet provided. The blood test will allow some providers to test for IgE antibodies produced if you have a food allergy.

What Does A Food Intolerance Test Do?

If you are asked for a blood sample, then the lab will be looking for specific IgE antibodies. They are immunoglobulins which are found in a too high frequency in the body when you have an allergy. A hair sample test will look at changes occurring at the cellular level. Different providers will test against different foods but some look at a staggering 350 foods. After the test you will receive a list of those foods which registered on the intolerance test. For some people that could be a very short list and the answer is very quick, for others the list could be longer but at least you will be able to start cutting out foods and getting to the bottom of the problem.
