Food Intolerance Testing

Food Intolerance Testing

Peanut food allergy concept

Is it Allergy or Intolerance/ Sensitivity?

There is considerable confusion between allergy & intolerance.The term Allergy is used to describe those cases in which the adverse reaction to food occurs almost immediately, usually within 1 hour. The reaction is obvious & often quite violent, for eg. developing a swollen lip or tongue after eating peanuts, or becoming violently sick after eating shellfish. True food allergies are quite rare & affect only a small percentage of the population

The term Food Intolerance, on the other hand, affects a great number of people. The symptoms of food intolerance rarely occur immediately after the food is eaten. In fact, the reaction is usually delayed by many hours or even several days. For example, the cheese eaten on Monday could be the cause of Wednesday’s asthma attack or Sinusitis. It is these delayed reactions which make the detection of the culprit foods a very difficult task without the help of expert laboratory testing.

Tests Available

Food Indicator Test 

This test is designed to simply give a Yes or No result to determine if a more detailed food test is necessary. If this indicator test result is No, you are unlikely to have an IgG mediated food intolerance. However, if the result is Yes, then a more comprehensive test is required to determine which foods are causing the elevated IgG antibodies. This Food Test defines food sensitivity / food intolerance as a food-specific IgG antibody reaction.

Low-Grade Inflammation Test 

Low-Grade inflammation (also known as high sensitivity-CRP inflammatory marker test) lurks silently below the surface, slowly & insidiously destroying tissue. It is the primary driving force behind many of the chronic, degenerative & autoimmune diseases of our time. This test measures the level of low-grade inflammation in your body. Many of the chronic conditions listed are rooted in inflammation.

Your food intolerance test will guide your food elimination diet. It is your guide, your road map to resolving this inflammation.

Pre-test Instructions

We recommend eating your normal diet leading up to the test. Get your doctor’s advice on any food you have excluded but want to re-introduce for the purpose of doing this test. If approved by your doctor, including one portion per day for 5-7 days before collecting the blood sample. Pre-test Food Suggestions;

However, to confirm if these are good alternatives for you, it is important that you include them in your diet for 5 to 7 days before doing the test.

These antibodies remain in your bloodstream for approximately 2-3 months. Your test will be assessing your reaction to foods you have eaten over that period. Check which foods are listed in the 93 & 200 Foods Test.

*Please note:  Allergy Testing – our tests are for food intolerance/ sensitivities & not food allergy testing. Please seek the advice of your GP before booking a test.

For children under 16yrs of age we need a GP referral & the letter must specifically request a food intolerance test. The GP must collect the blood sample. We will do the laboratory analysis & return the results to your GP.

Blood Collection & Aftercare

Working in conjunction with the Fitzwilliam Food Test Clinic, I will first assess your case. A blood sample will then be taken & sent for laboratory analysis. When the results are in I will interpret the readings for you and advise on how best to implement the necessary dietary changes.
