Food Allergy, Sensitivity and Intolerance Testing

Allergic Reactions...

An allergic reaction occurs when the immune system “overreacts” to a substance by identifying it as foreign, resulting in the synthesis and release of antibodies.  Antibodies in turn stimulate the release of chemicals such as histamine, which cause the typical array of allergic symptoms such as swelling, itching, a runny nose and watery eyes.  Eventually they can produce far reaching effects on the immune, endocrine and nervous systems.


The incidence of food allergies has increased dramatically over recent years, and it is now estimated that up to 20 percent of the population have adverse reactions to foods. Allergens (substances capable of producing allergic reactions), can be ingested, inhaled or absorbed through the skin.  From wheat and dairy products to the house dust mite, and from animal hair to pollens, we are all being bombarded by substances with the potential to cause allergic reactions.

Traditional Diagnosis can be Problematic. 

Traditional diagnosis of food hypersensitivity reactions is often based on skin prick tests, food diaries and lengthy food exclusion and reintroduction diets, which require a high level of compliance, and can be problematic.  Furthermore, it is virtually impossible to test all the different combinations of food types that may be contributing to the problems.



Dr Greenland offers a range of simple blood tests for food allergies, sensitivity and intolerances that includes panels for both immediate hypersensitivity reactions as well as for more delayed, gut associated intolerances related to ‘leaky gut’ syndrome.


These tests employ state of the art technology to measure the relative levels of antibodies and inflammatory markers to the most commonly encountered foods.

Food – Not Always Natures’ Medicine

Both food and environmental allergies have been implicated in a wide range of symptoms affecting every part of the body from mildly uncomfortable symptoms such as indigestion and gastritis to severe illnesses such as coeliac disease, arthritis and chronic infection. Allergies have also been linked to severe disorders of the central nervous system such as depression, anxiety and chronic fatigue. 

The Allergy / Sensitivity / Intolerance Testing Process

Initial Consultation

Dr Greenland recommends an initial 60 minute consultation during which he will take your full case history, and explore your dietary intake and symptoms in detail. If allergy testing is clinically indicated, he will explain the options available to you for testing, and answer any questions you may have. If you then wish to proceed, he will take the blood sample and send it for processing.

Follow up Consultation

Dr Greenland recommends a 30 minute follow-up appointment 10-14 days later, during which he can explain your test results in detail, and provide you with a comprehensive printed report. He will also work with you to formulate a bespoke food plan to reduce or eliminate exposure to any identified allergens, and thereby steer you towards optimal health and wellbeing. Subsequent follow up appointments can be arranged as required, to monitor and support you through this treatment process.

Allergy / Sensitivity and Intolerance Testing Price List

  • Food Sensitivity Profiles

    These panels measure the levels of specific IgE antibodies responsible for classical acute allergic reactions. These usually present immediately and include: hay fever, asthma, hives, swollen / itchy throat, tongue, lips, gums, watery / itchy/ swollen eyes, rhinitis, colic, anaphylaxis, eczema, and skin rashes:

    • IgE Food panel (37 Foods) (IMM05) – this is a more economical way of detecting allergic reactions to a smaller range of 37 common foods – £215.00*
    •  Nuts and Seeds (TDL-4A) – Almond, Brazil nut, Cashew, Hazelnut, Macadamia nut, Peanut, Pecan, Pine Nut, Pistachio, Poppy Seed, Pumpkin Seed, Sesame seed, Sunflower Seed, Walnut – £330.00*
    •  Shellfish (TDL-6A) – Clam, Crab, Crayfish, Lobster, Octopus, Prawns / Shrimp, Scallop, Squid – £211.50*
    • Finfish (TDL-7A) – Codfish, Mackerel, Plaice, Sardine, Pilchard, Salmon, Sole, Swordfish, Tuna – £211.50*
    •  Stone fruit / Rosaceae family (TDL-13A) – Almond, Apple, Apricot, Cherry, Peach, Pear, Plum, Raspberry Strawberry – £189.50*
  • Food Sensitivity Profiles

    These panels measure the IgG antibodies associated with ‘delayed’ food reactions that can exacerbate or contribute to many different health problems:

    • 75 Food ingredients (L-75) – £149.00* Show Tested Foods
    • 100 Food ingredients (L-100) – £199.00* Show Tested Foods
    • 150 Food ingredients (L-150) – £299.00* Show Tested Foods
    • Multiple Food Immune Reactivity Screen (C10) – This is the latest, state of the art, most comprehensive, and to the best of my knowledge, the most accurate on the market since it measures IgG and IgA antibody mediated reactions to 180 cooked, raw and modified foods, food enzymes, lectins and food additives, artificial colourings and gums £636.50*
  • Gluten Sensitivity / Coeliac Disease

    Coeliac disease is an auto-immune disease caused by an inability to properly digest foods containing gluten. Gluten is found in many grains including wheat, oats, rye, barley and spelt. Coeliac disease is chronic, has a genetic component and may affect several family members. It is a life-long condition in which the ingestion of the gluten component of wheat and related cereals leads to damage to the intestinal lining, skin reactions or the nervous system. Coeliac disease is not technically an ‘allergy’ to gluten per se.

    • Coeliac Disease Profile (TDL-GSA) – This profile is composed of a number of antibody markers to accurately distinguish between the presence or absence of gluten sensitivity and Coeliac disease – £160.00*
    • Comprehensive Coeliac Disease Profile (TDL-GSA2) – In addition to the antibody markers described in the TDL-GSA profile (above), this panel includes a genetic test for predisposition to Coeliac disease – £274.00*
    • Gluten Proteome Reactivity and Autoimmunity (C3) – This highly advanced panel accurately identifies gluten reactivity (including coeliac disease) by measuring IgG and IgA antibody production against 9 wheat proteins and peptides and 3 essential enzyme structures –  £391.16*
    • Gluten-Associated Cross Reactive Foods And Food Sensitivities (C4) – this is helpful for identifying cross-reactions to foods with a similar protein structure to gluten, and therefore provides valuable insights to those unresponsive or making limited improvements on a gluten free diet – £273.30* 
  • Environmental Allergy Profiles

    IgE Inhalant Profile (IMM06) – Identifies classical allergies to 27 of the most common airborne allergens. – £210.00*

  • Combined Panels
    •  IgG Foods + IgE Foods + IgE Inhalants (IMM24) – This profile consists of the IMM05, IMM06 and IMM12 panels described above, and therefore provides a comprehensive assessment of reactivity to foods and environmental allergens – £470.00*
    • Comprehensive Food Immune Reactivity Panel (C10C) – this highly comprehensive profile includes C3, C4, and C10C above, and is therefore a more economical way of obtaining a comprehensive picture of potential food reactivity – £1057.56*
  • Bespoke Allergy Testing

    Please get in touch if you can’t see an allergy test panel that meets your individual requirements. We can create a bespoke panel from an extensive repertoire of foods, food additives, environmental allergens (pollens, micro-organisms, mites, animals, insect venoms), occupational chemicals and drugs, as needed. Pricing for these is available on request.

* Prices quoted include test materials, the blood draw (carried out at Dr Greenland’s Chiswick clinic), specimen shipment / courier fees, laboratory processing fees, and a comprehensive printed report of the results. However preliminary and follow up consultations are not included. Please note that prices quoted above are subject to change at short notice, and so you should always contact the clinic for the latest information.
