Mediator Release Test (MRT®)

The best test & protocol for food sensitivities and reducing overall inflammation

Discover not just what you're reactive to, but what you're not. The MRT test evaluates 176 different food and chemical sensitivities. Our protocol emphasizes what you should eat, rather than just what to avoid, helping you build an anti-inflammatory diet tailored to your unique needs.

Gut Health Autoimmune Lab Blood Test
Your MRT test purchase includes:

  • Testing for 176 food and chemical sensitivities. The kit will be mailed to you within 7-10 business days. 
  • A physical copy of your results mailed to your house within 2-3 weeks.
  • Root Circle Community Resources:
    • A Root proprietary digital 20+ page interpretation and meal planning guide 
    • MRT interpretation video 
We have seen the most success using the Mediator Release Test (MRT) with the following conditions:

  • Irritable Bowel Syndrome with Diarrhea (IBS-D)
  • Hashimoto’s Thyroiditis
  • Rheumatoid Arthritis
  • Symptoms such as joint pain, brain fog, and fatigue
  • Migraines/headaches
  • Fibromyalgia
  • Weight gain due to inflammation
  • Various skin problems such as eczema, acne, and dry/itchy skin
This test might be for you if:
  • You are highly motivated to make major dietary changes for at least 6 weeks.
  • You are ready to feel better FAST. Most people see a 50-75% reduction in their initial symptom score within 14 days on the protocol.
  • There are no foods you wouldn’t be willing to give up for a short period of time (we are talking bread, alcohol, chocolate, and cheese, among many other foods.)
  • You are ready to start feeling amazing by improving digestion, reducing brain fog, increasing energy, and reducing joint pain (among many other possible improvements).
  • You are open to cooking very simple meals and snacks at home for at least 6-weeks.
This test might NOT be for you if:
We don’t recommend this test for strict vegans (your protein options may be very limited based on the results of your test and we may struggle to create a balanced meal plan).

PLEASE NOTE THIS KIT MUST BE DRAWN BY A PHLEBOTOMIST. IT IS NOT AN AT HOME TEST KIT.

Finding a Lab: The MRT test cannot be drawn at Quest labs. You can typically have this test drawn at any lab that does “outside draws.” We suggest calling ahead before showing up. Some people also seek out a mobile phlebotomist in their area. Here is a directory to search for a lab near you: 
Detailed instructions will be sent to you in a confirmation email post purchase. 

Restrictions: Not available in New York

**Please note that all test kits purchased through Root must be sent in to the appropriate lab within 6 months of purchase.**
