Food Intolerance Testing 

Are you suffering from any of the following:
 

  • Asthma

  • Abdominal Cramps

  • Bloating/Gas /Wind

  • Constipation/Diarrhoea

  • Headaches

  • IBS

  • Leaky Gut

  • Nausea

  • Sinusitis 

  • Skin complains/Eczema


Food intolerances can be the cause of a number of symptoms and identifying these specific foods or compounds can be a great first step to optimising health and vitality. After all how can the body heal itself whilst still being under attack?

Our nutritionist Jennie uses an in-clinic food intolerance test that measures Immunoglobulin G (IgG) antibodies to 59 specific foods, providing results while you wait..... A blood sample is obtained using a finger prick and this can identify potential "problem foods" for the individual, there is often a link with elevated IgG antibodies and inflammatory conditions within the body, manifesting in a range of health issues from digestive concerns to skin complaints.

 

The testing process is very quick and simple. If you prefer, a home test can be purchased and sent for you to take yourself and posted back in the free envelope provided.

Diagnosing food intolerances and eliminating them from the diet stops the body from being 'attacked', therefore allowing the body to heal. Specific compounds that are present in food and drinks can cause an acute onset of symptoms in some people whilst others may experience a delay by up-to three days from ingestion, this can often leave the client confused with pinpointing the trigger food. Over time, food intolerances can lead to leaky gut syndrome, low mood and low energy, as well as hormone disturbance and gut bacteria imbalance (dysbiosis). Many people feel they have IBS with instant feelings of bloating, gas, discomfort and abdominal pain.

*Please note that this is a food intolerance which uses Immunoglobulin E (IgE) NOT a food allergy test that uses IgA which is a faster acting and more severe response.

 

Frequently Asked Questions
Do I need to prepare for the test?
The only preparation for the food intolerance test is to ensure that you are sufficiently hydrated, this will allow the blood to flow easier and therefore speed up the process.

How long does it take to get the results?
40 minutes for in clinic results / 7-10 days for postal results.

What happens once I have the results?
You will receive a booklet with information about outlining the foods and the level of reactions to the specific foods.

What is the minimum age for an intolerance test?
2 years old.

What is an IgG?
IgG stands for Immunoglobulin (type G). Immunoglobulins are a class of proteins that function as antibodies produced by the immune system in response to foreign bodies entering the body. There are several different types of immunoglobulins with IgA, IgE, IgG, IgM being the most well-known.

Why do foods cause an IgG response?
Generally, foods are broken down during digestion into their component parts e.g. amino acids, glycerides etc. These pass harmlessly through the gut into the bloodstream. However, occasionally small fragments of partially digested or undigested foods are able to pass through the gut wall into the bloodstream where they are recognized by the immune system as being ‘foreign’. The immune system responds by making IgG antibodies to these foods.

Do high IgG antibody levels cause symptoms?
When a food causes the body to produce high levels of IgG then these antibodies combine with the protein in the food to form an ‘antigen-antibody complex’. These complexes are usually eliminated by other cells in the immune system. However, if the immune system is overloaded, these insoluble molecules become deposited in tissues within the body, where they may cause chronic inflammation and the subsequent production of symptoms.

Is it possible to have high IgG levels and not experience symptoms?
Yes, some people do have high IgG levels to certain foods but do not have any symptoms at all. This is most likely due to their immune system being extremely efficient at clearing away the antigen-antibody complexes before they have chance to be deposited in the tissues and cause a problem. While it is true that certain common foods are more likely to show a positive result e.g. wheat, dairy, soya. The reason for this is that these foods are consumed on a regular basis in our diet and along with digestive issues this can increase the likelihood that the body may react to them.

While an elimination diet will always be the gold standard, the benefit of doing a food intolerance test is that it will be able to quickly show which of the foods that are eaten on a regular basis, are a potential problem. In addition the tests are able to highlight more unusual foods which a person may not have considered removing from their diet.

Why test for IgG antibodies to foods?
The efficacy of a diet based on the measurement of IgG antibodies specific for food components has been demonstrated in a number of conditions, both in independent studies and clinical practice. Excellent results have been obtained in patients with migraine, IBS and obesity.

Can I take the test if I am pregnant?
A food intolerance test is not recommended during pregnancy as the immune system is suppressed. However, 4-6 weeks after giving birth should be fine.
