OBT MRT 176 Food Sensitivity Test USA (Blood Test-Most Popular) 146 Foods + 30 Chemicals


There is some debate over the accuracy of typical IgG antibody food sensitivity tests, that’s where the MRT 176 Food Sensitivity Test comes in! A much more accurate test that looks at over 146 foods and 30+ chemicals and additives. This is as comprehensive a food sensitivity test you will find anywhere. Comes with your own wallet size foods sensitivity guide, as a reference you can take with you when shopping or eating out! You will need to select a blood draw site (available across USA), as this is a blood test.

What is the Leap MRT 176 Food Sensitivity Test?

Traditionally, food sensitivities are tested by looking for antibodies to different foods in the blood. To get accurate test results, the person must have consumed enough of the food for a period of several weeks to produce enough antibodies for testing. This is ok if you currently eat the foods being tested and you don’t have a compromised immune system (taking steroidal anti-inflammatories, have autoimmune concerns, digestive issues, etc.). Food sensitivities are also more complex than just antibody production. There are many other inflammatory chemicals the immune system can produce that promote sensitivities. This is where the MRT test comes in. The MRT uses a much different, and more accurate, technique to identify type 3 and type 4 food sensitivities. The test also includes 30 food chemicals and additives to make sure you stay clear of those that impact your health the most. The MRT results also come with a wallet-size card with your sensitivities on them so you have a quick reference while grocery shopping.

How Does the MRT 176 Food Sensitivity Work?

The MRT test works by measuring the volume change of white blood cells when they are exposed to different foods. The more the cells are “empty”, the higher the assumed reaction. This is helpful since you don’t have to consume the foods and it can still be mostly accurate for those who have immune challenges.
