  • 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)
