What is food sensitivity or intolerance?

Your body may react badly to some foods, resulting in food sensitivity. Often the foods we regularly consume or the foods we crave are the ones causing us problems.

Research has shown that food sensitivities can be linked to IgG antibodies produced when these ‘problem’ foods are eaten. Normally these antibodies do not have any ill-effects, but if the immune or digestive system are not working optimally, their presence may provoke a wide range of symptoms. 

Food intolerance vs Food Allergy

When you have trouble digesting particular meals or food ingredients, it means you are intolerant to them. It’s not usually serious, but eating the food you’re intolerant to can make you feel unwell. Whereas food intolerance is different to a food allergy, which causes symptoms such as itchy skin, wheezing or swelling of the lips, face and eyes.

The food intolerance or sensitivity  test can provide individuals with an insight into the functionality of vital systems within the body. This test can help to guide specific nutritional and lifestyle modifications aimed at maintaining, or restoring optimal health and wellbeing.

How do I know if I have a food sensitivity?

Ask yourself if you have any of the following chronic unpleasant symptoms:








Irritable Bowel Syndrome (IBS)


Stomach cramps / abdominal pain

Know Faster


Tests that are run in-clinic, help to give healthcare professionals access to results that can be interpreted while the client is present. This enhances the client experience and allows immediate guidance to be given.

Food Intolerance Test is an In-clinic test that measures IgG antibodies to 40+ specific foods. It provides results within 60 minutes. It includes some of the most common foods such as wheat, gluten, yeast, soya and dairy. It is a rapid test.

Know More


It is a highly sensitive and accurate laboratory service that detects the presence of IgG food specific antibodies to more than 200 foods. The health practitioner collects your blood sample and sends it to the laboratory for food intolerance or sensitivity testing. The test results will be emailed to you and your health practitioner within 7–10 working days.

Choose from a range of options and prices for testing from 120 to over 200 Foods. You get your food intolerance test results within 7-10 working days.

Frequently Asked Questions

1. 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.

2. 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 can 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.

3. 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 several conditions, both in independent studies and clinical practice. Excellent results have been obtained in patients with migraine, IBS and obesity.

4. 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 ok.


5. What is the lower age limit for testing?

We do not recommend testing on children under the age of 2 years.

6. How does the test work?

Food extracts are 'printed' onto nitrocellulose 'pads'™ on a glass microscope slide, together with calibration standards and controls. A blood sample provided by the patient is diluted and dispensed onto each printed microarray. Food IgG antibodies, if present, bind to the food extracts and the results are measured by a high-resolution scanner, before being calibrated against the standards using the Footprint reporting software to give quantitative results. This software then produces a tailor-made printout of the final food IgG antibody result for each food on the requested food panel.


7. Do you need to re-introduce foods before taking a test – if so, how long for?

In general, we recommend that you follow your normal diet, so that the test will reflect what you usually eat. However, if you have specifically avoided a food for more than three months e.g., cow's milk, which used to be part of your normal diet and you would like it tested, we would recommend it is reintroduced. The recommendations are to reintroduce the food for 1 week eating a normal portion of that food at least once daily before taking the test. If symptoms occur once the food is re-introduced, we recommend that you discontinue that food and conclude you are still intolerant to it.
