Do Food Intolerance Blood Tests Work

A food intolerance occurs when your body, for whatever reason, struggles to properly digest a certain food or food component. This frequently results in gas, bloating, constipation, diarrhea and/or headaches.

One of the hallmark characteristics of food intolerance is that it is dose-dependent, meaning that small amounts of a potentially bothersome food may not cause you issues, while moderate to larger amounts will.

A food intolerance, while unpleasant and uncomfortable, is not life threatening. Whereas a food allergy is an immune, rather than purely gastrointestinal response to food, and can be life threatening.

In addition, while you can test for food allergies, there is no formal test that can be done to test for food intolerance. Symptoms of food intolerances also tend to take long to appear than symptoms of allergies.

The best diagnostic tool is an exclusion diet, also known as an elimination or diagnostic diet. In a typical exclusion diet, the suspected food is removed from the diet for a set period, usually between 2 weeks and 2 months. I during this period the adverse reactions resolve, it becomes more likely that the culprit has been found. This can be further confirmed if it is then reintroduced and symptoms return.
