If you’ve been dealing with stubborn digestive issues, recurring headaches, low energy, or skin flare-ups—and you suspect something you’re eating might be part of the picture—you’re not alone. Many people spend years cutting foods in and out of their diet by guesswork, never quite pinpointing the trigger. MRT (Mediator Release Test) food sensitivity testing is one tool that aims to take some of the guesswork out of that process, and it’s now available through Sarasota Compounding Pharmacy right here in Sarasota, FL.
Below, we’ll walk through what MRT testing is, what it’s used for, how it works with the LEAP protocol, what its real benefits and limits are, and how to get started locally.
What Is MRT (Mediator Release Test)?
MRT is a blood test designed to measure your body’s inflammatory response to a wide range of foods and food chemicals.
When your immune cells react to a food you’re sensitive to, they release inflammatory “mediators”—substances such as histamine, cytokines, leukotrienes, and prostaglandins. MRT is built to detect the degree of that mediator release across roughly 170 different foods and food chemicals in a single panel.
Foods are then sorted into simple, color-coded categories—typically non-reactive (“green”), moderately reactive (“yellow”), and highly reactive (“red”)—giving you and your practitioner a clear starting map for building a personalized eating plan.
The important distinction:
MRT is a food-sensitivity tool. It is not an allergy test and it is not a medical diagnosis.
Food Sensitivity vs. Food Allergy vs. Food Intolerance
These three terms get used interchangeably, but they’re different—and knowing the difference is key to understanding what MRT can and can’t do.
- Food allergy — An immediate, IgE-driven immune reaction (hives, swelling, and in severe cases anaphylaxis). True allergies are diagnosed by an allergist using validated IgE testing. MRT does not test for allergies.
- Food intolerance — A non-immune reaction, such as lactose intolerance from an enzyme deficiency. This is typically identified through other methods.
- Food sensitivity — A delayed, often lower-grade inflammatory response that may show up hours or even days after eating, making it difficult to trace. This is the category MRT is designed to help explore.
If you suspect a true, immediate food allergy, please see a physician or allergist—MRT is not a substitute for that evaluation.
What Is MRT Testing Used For?
MRT is most often used by people who suspect that food may be contributing to chronic, hard-to-pin-down symptoms. Individuals exploring MRT and the LEAP protocol commonly report concerns such as:
- Digestive discomfort (bloating, cramping, irregularity, symptoms associated with IBS)
- Recurring headaches or migraines
- Fatigue and low energy
- Joint aches and general inflammation
- Skin issues such as eczema or breakouts
MRT doesn’t diagnose any of these conditions. Instead, it’s used to help build a personalized elimination diet so you and your practitioner can systematically test whether reducing certain foods makes a difference in how you feel.
How MRT and the LEAP Protocol Work Together
MRT results are the starting point; the LEAP (Lifestyle Eating and Performance) protocol is the plan you build from them. Guided by a trained practitioner, LEAP is a phased, personalized elimination-and-reintroduction diet:
- Start with your least-reactive foods.
- Reintroduce methodically.
- Refine and personalize.
Because MRT also highlights your best-tolerated foods, LEAP focuses on what you can comfortably eat—not just a long list of what to avoid.
The Benefits of MRT Food Sensitivity Testing
For the right person, MRT-guided LEAP can offer some real practical advantages:
- Less trial-and-error. Instead of eliminating dozens of foods blindly, you start with a focused, data-informed plan.
- A personalized roadmap. Your results are specific to you—no generic “avoid gluten and dairy” template.
- A focus on your safe foods. Knowing your best-tolerated foods makes the plan easier to actually follow.
- Professional guidance. The protocol is meant to be run with a trained practitioner, so you’re not interpreting complex results alone.
- A structured way to test a hunch. If you’ve long suspected food is a factor, MRT + LEAP gives you an organized process to find out.
Being Honest About What MRT Is—and Isn’t
We believe good patient care includes clear expectations, so here’s the straight talk:
- MRT is a food-sensitivity guide, not a diagnostic test.
- It is not an allergy test.
- It is typically not covered by insurance.
- Results guide a diet—your body confirms the answer.

Frequently Asked Questions About MRT Testing
What is MRT testing?
MRT (Mediator Release Test) is a blood test that measures how strongly your immune cells react to about 170 foods and food chemicals by detecting the release of inflammatory mediators. It’s used to help build a personalized elimination diet.
Is MRT the same as an allergy test?
No. MRT looks at delayed food sensitivities, not IgE-mediated food allergies. If you may have a true food allergy, see a physician or allergist for validated allergy testing.
What symptoms do people use MRT for?
People often explore MRT when they suspect food may contribute to chronic issues like digestive discomfort, headaches or migraines, fatigue, joint aches, or skin flare-ups. MRT does not diagnose these conditions; it helps guide a diet to test them.
How does the LEAP protocol work?
LEAP is a phased, personalized elimination-and-reintroduction diet built from your MRT results. You start with your least-reactive foods, then methodically reintroduce others to see how your body responds.
Is MRT testing covered by insurance?
Usually not. MRT is generally considered an out-of-pocket wellness service, though many patients pay using an FSA or HSA card. We’ll go over pricing with you before you commit.
How soon might I notice a difference?
It varies from person to person, and results are not guaranteed. Because food sensitivities are individual, the reintroduction phase is what ultimately reveals what works for your body.
