Greenfields Clinic announce a test for IgG food intolerance which can now be done with a fingerprick sample instead of a venipuncture. The test is carried out at the specialist ProImmun lab in Germany, which uses only organic foods for testing. This avoids the potential cross-reactivity with pesticides, fungicides and herbicides that could happen with intolerance tests that use conventionally-farmed foods for testing. Using the food intolerance test in practice, our naturopaths have found the test highly sensitive and effective for patients with food intolerance in practice, as the test results for IgG (Immunoglobulins) 1-4 can also test for Candida Albicans yeast, as well as aspergillus niger, a mold that grows on some grains during storage. This can highlight a separate reason for intolerance to certain grains that would not otherwise show up in tests for the specific foods only. The ProImmun test results come with an optional food rotation plan with recipe book, and is the only intolerance test that can automatically remove from your food recommendations list the foods that contain aspergillus niger if you show an intolerance to it, or remove foods with known allergic reactions that may not also show up as intolerances, such as gluten (for people with coeliac disease) or dairy products (for people with lactose intolerance). The test also has the option to remove items from your food list which are high in histamine for people who have histamine-type symptoms such as headaches, rashes, itching, diarrhoea and abdominal pain, a different mechanism to IgG intolerance. These options can make the shopping list and rotation plan much more personalised to you.

This test was previously only available with a venipuncture blood sample, but now the fingerprick test kit allows patients to do the test at home with just six drops of blood and send the sample to the lab by post, also saving on the cost of the courier.

The ProImmun food intolerance test uses enzyme immuno-assay is available with the following number of foods tested: 
  • Pro-Immun Slim, 44 Antigens (recommended for children), includes milk, gluten, eggs and soya.
  • Pro-Immun, 91 Antigens includes as above, bananas, apples, lemons, garlic and some poultry.
  • Pro-Immun M, 181 Antigens (plus optional recipe book and food rotation plan), includes as above, pulses, grains and a range of fish.
  • Pro-Immun M-Plus, 270 Antigens (plus optional recipe book and food rotation plan), includes as above, tea, seafood, herbs, spices, a range of seasoning ingredients, selected E numbers and aspergillus niger.

N.B. IgG food intolerance testing looks for what is known as delayed hypersensitivity, it is not immediate hypersensitivity (IgE allergy), which includes hives, asthma, and potentially fatal, systemic allergic reactions (anaphylaxis) most often to peanuts, fish, seafood, or tree nuts; infants’ respiratory, skin, or digestive problems often due to ingestion of wheat, dairy, corn or soya in foods or  breast milkIgG food intolerance does not include adverse reactions from naturally occurring chemicals in foods, including salicylates, theobromine in chocolate, caffeine in coffee, solanines in nightshades, and tyramine in cheese. IgG intolerance does not cover reactions to food additives, including artificial colours, preservatives, flavours and sweeteners, monosodium glutamate (MSG), nitrites, and sulfites. IgG intolerance does not reveal the cause of symptoms resulting from impaired digestion, including deficient digestive enzymes or hydrochloric acid, lactose intolerance or malabsorption from a variety of digestive diseases (Crohn’s disease, coeliac disease, colitis, etc.). To investigate any of these may involve other testing, please contact our naturopaths for further information.

IgG testing should not be carried out if you have a raised temperature or have taken steroids or chemotherapy within the last four weeks, as the reactivity will not be as strong due to suppression of the immune system.
