Food Intolerances Testing

We use advanced lab testing techniques, which help to produce the most accurate results available on the market. 



There are three major antibodies that are produced in food sensitivities and food allergies – IgE, IgG and IgA.

The IgE antibodies are normally produced in an allergic reaction. These are the antibodies normally screened for by conventional medicine and will not show if you have a food intolerance.

Testing for adverse food reactions is useful for individuals who suspect that a food is responsible for causing their symptoms, but can't quite identify which food(s). The presence of circulating antibodies may affect each patient differently. Circulating IgG food antibodies are not diagnostic for a specific condition, but indicate an immune response to that food. The immune response could be a normal response that would not necessarily cause symptoms.  


Food Antibodies tests

These tests measure the most commonly found antibodies in a food intolerance. Their presence indicates that the food particles have passed through the gut lining and are causing systemic inflammation and/or autoimmunity.

  • Regenerus P88 dietary antigen test (blood serum) £335


Cyrex Tests & Arrays

The cyrex food sensitivity test uses advanced lab techniques, producing the most accurate results available on the market. The test involves a full blood test and looks for IgA and IgG antibodies in combination.

IgA antibodies are involved in the defense of the mucosal membranes and their presence indicates inflammation in the gut; helping to identify food sensitivities before they become more systemic.

IgG antibodies, are the most common antibody found in a food intolerance. Their presence indicates that the food particles have passed through the gut lining and are causing systemic inflammation and/or autoimmunity.

Cyrex also tests food in their raw and cooked forms; reactivity to common food combinations; and reactivity to gum molecules and binding isolates.

Cyrex arguably provides the world's most advanced immunological testing services, which include markers for gluten, gluten-linked food intolerances and multiple food sensitivities, "leaky gut", IBS, SIBO, auto-immune disorders, pathogens such as parasites, moulds, viruses and bacteria, blood brain barrier breakdown and other neurological disorders for example those arising from viral infection and/or toxins, as well as those relating to Alzheimer's Disease.

Considerations: Please note that the enquiries team are able to guide you in the right direction with Cyrex testing but cannot choose which Array is best for you. These tests are complex so we would advise that you see a practitioner for an initial consultation first to ensure you are doing the correct Array for your health concerns., get in touch today

*Please be advised that this is only a small range of tests available. We would generally recommend the most appropriate testing following a full health assessment and the practitioner will always work with your budget.
