  • ProImmune M® test is an IgG food intolerance test from the Proimmun Laboratory in Pirmasens, Germany
    • Pro Immune M® tests for IgG 1 – 4 antibodies, looking for delayed defensive reactions that start 4 – 72 hours after an antigen has been consumed. The antibodies are isolated from the patient’s blood and brought into contact with food proteins, under the guidance and supervision of a specialist laboratory doctor
    • Most antigens in the Pro Immune M® test are foods, but also included are Candida Albicans yeast and aspergillus niger, a mould 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 food proteins used in the test are organic. This avoids potential cross-reactivity with pesticides, fungicides and herbicides that could occur with intolerance tests that use conventionally-farmed foods for testing
    • Detailed test results show the strength of the immune system reaction to a food, graded from 1 (weakest) to 3 (strongest), allowing you to prioritise food elimination
    • Test results are accompanied by a personalised food rotation plan, shopping list and an optional recipe book, all of which exclude foods that Pro Immune M® has revealed as causing intolerances. You can also choose to exclude other foods from these, regardless of the Pro Immune M® findings – for example, due to previous diagnoses such as a food allergy (IgE mediated test results)
    • The Pro Immune M® test is available in the following profiles:
      • 43 antigens (suitable for children)
      • 91 antigens
      • 181 antigens (recipe book available)

Phlebotomy service

A blood draw service is available for blood tests requested by our practitioners and for adults referred to Greenfields by practitioners from other clinics.

If you have been referred by an outside practitioner you can call reception on 01227 454 848 or book a blood test online. Please establish in advance whether the sample needs to be centrifuged (for an additional charge), whether you need to be fasting for the test, and how you will get the sample to the laboratory.

Some tests are available by fingerprick blood sample so you don't have to have a venipuncture, please ask for details.
