MRT Food Sensitivity Testing: Find Your Trigger Foods
MRT Food Sensitivity Testing

Find the Foods That Are Working Against You

The Mediator Release Test (MRT) is the most advanced food sensitivity test available. It identifies which specific foods and chemicals trigger an inflammatory response in your body so you can stop guessing and start feeling better.

What Is the MRT Food Sensitivity Test?

The MRT (Mediator Release Test) is a blood test that measures your immune system's inflammatory response to 170 different foods and food chemicals. It is the most accurate food sensitivity test available, with 94.5% sensitivity and 91.7% specificity.

Food sensitivities are different from food allergies. Allergies cause an immediate reaction (think hives or throat swelling). Sensitivities trigger a delayed inflammatory response that can show up hours or even days later, making them nearly impossible to identify through elimination alone.

The MRT does not just tell you if you are reactive. It shows you the degree of your reaction to each food, color-coded as green (safe), yellow (moderate), or red (reactive). This gives you a clear roadmap for which foods to eat and which to avoid.

What Your MRT Results Show You

Reactive Foods (Red)

Foods that trigger a significant inflammatory response in your body. These are the ones causing or worsening your symptoms and should be removed.

Moderate Foods (Yellow)

Foods that trigger a mild to moderate response. These are introduced back gradually once your system calms down.

Safe Foods (Green)

Foods that do not trigger an inflammatory response. These form the foundation of your personalized eating plan.

Food Chemicals

Tests for reactions to common additives like MSG, food colorings, preservatives, and other chemicals found in processed foods.

Personalized LEAP Protocol

Your results come with a structured eating plan that starts with your safest foods and systematically reintroduces others over time.

Inflammation Patterns

Reveals whether your immune system is in a heightened state of inflammation overall, which affects energy, mood, and recovery.

Signs This Test Might Be Your Next Step

You do not need to check every box. If even a few of these sound like you, this test could provide the clarity you have been looking for.

Bloating or digestive issues after eating
Migraines or chronic headaches
Skin flare-ups (eczema, acne, rashes)
Joint pain or body aches
Fatigue after meals
Brain fog that comes and goes
IBS-like symptoms
Feeling worse despite eating 'healthy'

Frequently Asked Questions

How is MRT different from IgG food sensitivity testing?

IgG tests measure antibody levels, which can reflect exposure rather than true sensitivity. MRT measures the actual inflammatory mediators released by your immune cells when exposed to foods. This makes it a more accurate measure of how your body truly reacts.

How many foods does it test?

The MRT tests your reaction to 170 foods and food chemicals, covering a wide range of common and less common triggers.

How long until I feel better?

Many women notice significant improvement within the first 10 to 14 days of following the LEAP protocol. Some symptoms like bloating and headaches can improve even sooner.

Can I still eat out and have a social life?

Yes. The protocol is structured but flexible. We work together to make it practical for your real life, including dining out and family meals.

Is this the same as a food allergy test?

No. Food allergies involve an IgE immune response (immediate, potentially severe). Food sensitivities involve a different immune pathway and cause delayed, chronic symptoms. MRT tests for sensitivities, not allergies.

What if I have already tried an elimination diet?

Elimination diets require you to guess which foods are problematic. MRT removes the guesswork by showing your exact reactions. Many clients who struggled with elimination diets find success with MRT because it is specific to their body.
