What To Do Before A Food Test

Please note that this test works by measuring how you respond to foods that you have eaten. We do this by laboratory testing for antibodies. Therefore, it is important to follow your normal diet before taking the test so that the test results will reflect what you usually eat.
Do not eat any food which has already caused a severe reaction without first getting a medical opinion.

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, include one portion per day for 5-7 days before collecting the blood sample.


  1. Cow’s milk (dairy products) can be problematic for some people and goat’s products (cheese, yogurt) are for many people a good alternative.
  2. Soya products and especially organic soya is another good alternative.
  3. Potato intolerance is common and sweet potato is a possible alternative.
  4. Spelt bread makes for a good alternative for wheat sensitive people.
However, to confirm if these are good alternatives for you it is important that you include them in your diet for five to seven days before doing the test.
These antibodies remain in your bloodstream for approximately two to three months.  Your test will be assessing your reaction to foods you have eaten over that period.

Food Sensitivity Testing

In many cases, conditions such as irritable bowel, asthma, eczema, psoriasis, arthritis, sinusitis, migraine etc are different manifestations of inflammation caused by food intolerance.

If the problem foods can be identified accurately and removed from the diet, there will be a very significant improvement in health.

Conditions relating to food sensitivity begin when the digestive system is no longer able to process particular foods as they pass down through the digestive tract. The end result is the build-up of many poisonous intestinal toxins.

Treating Thyroid Disease

Thyroid disease is typically a malfunction of the thyroid gland, where the immune system destroys or stimulates thyroid tissue. It is almost always caused by the autoimmune condition Hashimoto’s Thyroiditis, in which the body’s immune system reacts against the thyroid gland gradually making it inactive and causing hypothyroidism, or by Graves Disease, where the production of thyroid hormone is stimulated causing hyperthyroidism.

Thyroid autoimmune conditions are as a result of your immune system sending out antibodies to attack the thyroid gland.

Intolerance Indicator Testing (NEW)

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 sensitivity.

Low Grade Inflammation Testing (NEW)

Most of the time, inflammation is a lifesaver because it enables your body to fend off various disease-causing bacteria, viruses and parasites. The instant any of these deadly microbes enters your body, your defences destroy them by a process known as inflammation.

Once the invading microbes are killed, the inflammation process shuts down and healing begins. Every once in a while, however, the whole feverish production doesn’t shut down on cue. The inflammation becomes chronic rather than transitory.

Candida Albicans Testing

Candida Albicans is a yeast-like fungus that is normally present on the skin and on mucous membranes such as the vagina, mouth, or rectum. An overgrowth of Candida in these areas is commonly referred to as thrush. It is also a normal inhabitant of the human gut.  As a scavenger organism, it feeds off undigested food waste in the gut. Candida Albicans can then change its form to become a pathogenic (injurious) invasive fungus.

The test is designed to detect elevated levels of IgM and IgG antibodies to Candida Albicans. Elevated IgM results indicate an early stage infection. Elevated IgG results indicate an active ongoing infection or the occurrence of a past infection.

Coeliac Testing

Coeliac Disease (CD) is a permanent disease of the small intestine, caused by a reaction to the gluten found in wheat, rye and barley. The intestinal lining is subjected to severe attack as a result of the gluten. The intestinal lining becomes leaky and loses its ability to absorb nutrients from food.

Vitamin D Testing

Vitamin D deficiency can be a serious problem and does not have very obvious symptoms. It increases susceptibility to other more serious conditions. Maintaining Vitamin D levels protects the body from a wide range of diseases including viruses, cardiovascular disease and bone disease including osteoporosis.

The long Irish winter and the lack of sunlight is perhaps the biggest cause of Vitamin D deficiency amongst people living in Ireland. That’s why we should be more concerned than most countries.

About Food Intolerance Testing


This build-up of toxic, undigested food within the intestines will irritate the gut wall making it permeable.  This allows undigested foods and toxins to make their way into the bloodstream. These toxins are then carried throughout the body and may cause infection, inflammation and may trigger autoimmune disease.

If the problem foods can be identified accurately and removed from the diet, there will be a very significant improvement in health.

Our food intolerance testing will guide your food elimination diet and consequently, help you to find the particular foods that are causing this toxic state.

Fitzwilliam Food Test Clinic  Dublin defines food sensitivity (intolerance) as a food -specific IgG Antibody reaction.  Please note that food allergy is totally different to food intolerance.

Before Taking A Food Sensitivity Test


This test works by measuring your response to food so it is important to eat a broad range of foods beforehand.

Click here for the list of foods tested on our 93 food test and our 200 food test

Do not eat any food which has already caused a severe reaction without first getting a medical opinion.

Consult your GP before booking a food sensitivity test.


Follow Up After Taking the Test


To get the best results from your food intolerance testing report you will need to have your progress supervised over an extended period of time. We recommend that this is best done by your own general practitioner.

Your GP may in turn refer you to a  nutritionist who can monitor and assess your progress into the future and offer long term nutritional support.

About Low Grade Inflammation


A pathological feature of a host of chronic diseases

Introduction

This graphic alerts us to the fact that low grade inflammation is the primary driving force behind many of the most common,  chronic conditions of our time. Low grade inflammation begins in the gut and diet is central to this. Your food test is your road map to resolving this inflammation.

What is low grade inflammation?

  • You can’t feel it
  • Lingers for years, silently and insidiously damaging organs and body tissues
  • When it has done sufficient organ / tissue damage – chronic disease emerges
  • It is primarily driven by the foods you are eating
  • Ensure that your hs-CRP ( high sensitivity ) inflammation test  score is less than 0.5 mg / L – the optimal level

Low grade inflammation is the reason why you :

  • Gain weight
  • Suffer low energy levels and poor concentration
  • Become sick
  • Age faster

Low Grade Inflammation Test (hs-CRP)

This test is designed to measure a very specific inflammatory marker known as CRP. This new test is a specialist “high sensitivity” version of the standard inflammation test and is referred to as hs-CRP. It will accurately measure your low grade inflammation status. High levels of this type of inflammation are associated with the conditions listed.
The test will grade your risk as:

crp-4-levels-of-inflammation

All that is required is a small finger-prick sample of blood to do the analysis.
