Food sensitivity or food intolerance is not the same as having a food allergy. People with food sensitivities are either unable to effectively breakdown a specific component of food or their immune system may react with particular components in food. This test may be particularly beneficial to those who experience symptoms such as headaches, stomach pain and other digestive symptoms after consuming certain foods. Food groups identified in this test as reactive can be used to develop an elimination diet to rule out potential food suspects.

What’s included in this test?

  IgG antibody reactivity to 108 foods

This test measures the presence of IgG antibodies in your blood. Based on IgG reactivity each of the foods tested will be classified into a group:
Group 1 – low reactivity;
Group 2 – moderate reactivity;
Group 3- high reactivity.

Foods found in the high reactivity group may be behind your digestive issues and would make ideal candidates to be tested in an elimination diet. This is not an allergy test. It will also not determine whether you are lactose intolerant or have celiac disease.
