Food intolerances are put into two main categories: permanent and concealed.
- Permanent food intolerance
It’s estimated that about five percent of food intolerance test results are for people who have a permanent food allergy. Usually the person knows they are allergic to the food in question, but the test will confirm this so that they can avoid the problem food.
The rest of the cases that a food intolerance test discovers are called concealed allergies or intolerances. The person usually doesn’t know what food makes them sick or allergic and so they have to do the food intolerance test to figure it out. Usually it is something that the person eats often.
Food Intolerance Test Procedures
In one kind of food intolerance test, allergens from various common foods are mixed with a person’s blood and this is incubated and watched with a special phase contrast microscope. If the food allergen shows a toxic reaction the white cells will die and/or the blood platelets will clump up in a mass. If not, the blood sample will stay normal.
The blood test version of the food intolerance test is estimated to have a 70 percent rate of success in diagnosing the foods that the person is allergic to or can’t tolerate for whatever reasons. It is considered more accurate than the skin test, which is estimated to be only 20 percent accurate.
List of Foods Tested
The Comprehensive Food Intolerance Test tests for 113 foods, including various types of meat and fish, dairy products, fruits and vegetables, nuts and grains, and herbs and spices.
