The MRT requires a blood sample, typically drawn from a vein in your arm and collected using a kit from the company that has a patent on the test.If your white blood cells “shrink” when exposed to a food antigen in the MRT Test, it causes a change in the solids (white blood cells) to liquid (plasma) ratio of your blood sample, which is measured to determine your reactivity to the food.When your white cells shrink upon exposure to a food antigen, it suggests they’ve released chemical mediators, such as histamine and leukotrienes, that could provoke symptoms in your body.
The diet based on your MRT results is called LEAP (Lifestyle Eating and Performance) and is directed by health practitioners, such as dietitians, trained in the test and its interpretation.A small study presented at an American College of Gastroenterology conference found that people with irritable bowel syndrome (IBS) who followed an elimination diet based on MRT results for at least one month reported a 67% improvement in gut issues, such as diarrhea.However, there was no control group in this study, nor has it been published in full. Furthermore, PubMed, a large database that indexes published medical studies, lists no studies on the MRT test.
