    MRT Food Sensitivity Testing & Personalized Nutrition

    Identify potential dietary triggers, calm chronic inflammation, and build a sustainable nutrition plan. Unscripted Medicine offers Mediator Release Testing (MRT) and personalized nutrition guidance for patients across North Dallas, Frisco, Plano, Addison, Richardson, and Carrollton.

    What Is MRT Testing?

    MRT (Mediator Release Test) is a patented, blood-based food sensitivity test that evaluates the body's inflammatory response to a wide range of foods and food chemicals. By measuring how white blood cells react when exposed to specific triggers, MRT helps quantify dietary reactivity in a way that traditional allergy testing cannot.

    Food Allergies

    IgE-mediated immune responses that may cause rapid, sometimes serious reactions such as hives or anaphylaxis.

    Food Sensitivities

    Delayed, non-IgE inflammatory responses that may contribute to chronic, low-grade symptoms—what MRT is designed to assess.

    Food Intolerances

    Non-immune reactions, often related to enzyme deficiencies (such as lactose intolerance), distinct from allergies and sensitivities.

    Mediator Release Testing Explained

    When the immune system reacts to a food or food chemical, white blood cells release inflammatory mediators—chemicals that can drive symptoms throughout the body. MRT measures the volume of mediator release in response to a broad panel of foods and additives, helping categorize them as reactive, moderately reactive, or non-reactive for each patient.

    Inflammation & Immune Reactivity

    Chronic, low-grade inflammation can influence digestion, energy, mood, joint comfort, and skin clarity. Identifying reactive foods is one tool for reducing dietary contributors to inflammation.

    Personalized Nutrition Planning

    MRT results are used to design a personalized nutrition plan—often called the LEAP (Lifestyle Eating and Performance) approach—centered around your least reactive foods.

    Elimination & Reintroduction

    A structured elimination and reintroduction process helps confirm individual tolerance and rebuild a varied, sustainable, anti-inflammatory diet over time.

    Functional Medicine Nutrition Support

    MRT is one part of a broader, root-cause strategy—integrated with gut health, hormones, sleep, stress, and lifestyle for long-term wellness.

    Gut Health Connections

    Food sensitivities often go hand-in-hand with underlying gut imbalances. Conditions such as dysbiosis, intestinal hyperpermeability, and chronic inflammation can amplify immune reactivity to foods. For this reason, MRT is frequently paired with comprehensive gut evaluation—including GI-MAP microbiome testing and our broader Gut Health for Modern Longevity approach.

    Concerns MRT Testing May Help Investigate

    • Bloating and digestive symptoms
    • Headaches and migraines
    • Fatigue and brain fog
    • Joint discomfort
    • Skin concerns such as acne, eczema, and rosacea
    • Other chronic inflammatory symptoms

    MRT is not appropriate for every patient. Testing recommendations are personalized based on symptoms, history, and clinical evaluation.

    Long-Term Wellness and Longevity

    The goal of MRT and personalized nutrition is not lifelong restriction—it is reducing inflammatory triggers while supporting the gut, immune system, and overall resilience. Over time, many patients are able to reintroduce a wider variety of foods as their underlying inflammation calms and their gut health is restored.
