MRT Food Sensitivity Test Most food sensitivity tests measure a single immune pathway — IgG antibodies — which covers only a fraction of how the body actually reacts to food. The Mediator Release Test (MRT) measures the end result of all immune pathways simultaneously: when your blood is exposed to each of 176 foods and food chemicals, the test quantifies how much your white blood cells shrink, reflecting the actual inflammatory mediator release. The result is a more complete and clinically accurate picture of food-driven inflammation than IgG testing alone. Foods are categorized as reactive (red), moderately reactive (yellow), or non-reactive (green), providing a clear roadmap for an elimination protocol. This test requires a blood draw, completed through a mobile phlebotomist. Once you have your results, you can add on a new patient session with a Nuvitru provider to build your personalized elimination and reintroduction plan. Mobile phlebotomy required (fee not included) | 176 foods and food chemicals tested Testing does not replace diagnosis or treatment from your physician. Availability, requisition requirements, and state restrictions should be confirmed before fulfillment.
