Ordering the MRT Test
Most food sensitivity tests rely on measuring antibodies in the blood. For accurate results, you must have consumed the food consistently for several weeks to trigger a detectable immune response. The Mediator Release Test (MRT test) eliminates this requirement, making it a more convenient and dependable option.
Ordering the MRT test is also a much better choice for those with immune-related issues like autoimmune conditions, digestive disorders, or the use of steroidal anti-inflammatories. Consult your doctor just in case they want to make some adjustments before taking the lab test.
Food sensitivities are often associated with gas, bloating, inflammation, diarrhea, and other G.I. issues, which is why our clinical team suggests pairing this test with the GI Map stool test to assess gut bacteria.
How Does the MRT Test Work?
Food sensitivities involve more than just antibody reactions; your immune system can release various inflammatory chemicals that contribute to symptoms. The MRT test goes beyond antibody detection by measuring immune cell chemical release to identify food sensitivities that traditional antibody testing often overlooks.
Imagine popping a ball to see what’s inside. Your immune cells are like balls filled with different chemicals, and when they react to a food or additive, they release their contents. The MRT measures the size of the balls after being exposed.
Not only does the Mediatory Release Test include 146 foods, it also tests for 30 food chemicals and additives to help you identify and avoid triggers that most significantly affect your health. Additionally, MRT results include a wallet-sized reference card, making it easy to remember your sensitivities while shopping.
Preparations Before Taking the Test
Pairing for the MRT Test is very easy. Fasting is not required, and there are no dietary restrictions before the test. Continue all medications unless instructed otherwise by your doctor.

Are there panels with fewer food markers?
Yes. Try the MRT 130 or the MRT 85.
How often should I retest?
Retesting the Mediator Release Test is recommended approximately every six to twelve months, depending on symptom changes and dietary modifications. As immune responses can shift over time, regular testing helps track progress and refine dietary strategies for long-term symptom relief and improved well-being.
How accurate is the test?
The MRT test uses an advanced method called volumetric measurement of mediator release, which quantifies immune cell reactions to different foods and food chemicals. It has a 94.5% sensitivity and 91.7% specificity. TrueHealthLabs.com only partners with CLIA-certified laboratories like Oxford Biomedical that uphold high testing standards for dependable results.
Can someone interpret my test results?
Yes. We have a clinic team that can go over your results with you in person. Add on the “Results Review” at the top of the page. Here are the details for the one-on-one results review.
Other important MRT Notes:
