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.

Thyroid Autoantibody Testing

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.

The new thyroid autoantibody test is able to detect these antibodies sent out to attack the thyroid gland. Early detection of raised thyroid antibody levels can often precede the onset of symptoms by a year or more. The presence of these thyroid antibodies unequivocally confirms the diagnosis of thyroid disease.

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

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.

This food test 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.

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 test 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.
