Allergic reactions to food and inhaled particles occur when the immune system is triggered to release antibodies. The two most commonly produced antibodies are immunoglobulin G (IgG) and immunoglobulin E (IgE) antibodies.

The clinic offers 96 IgG Food Allergy Testing in both a standard and vegetarian option.

IgG Reactions 

IgG reactions may occur gradually over hours or days. Because of this delay, it is often difficult to isolate the offending allergen. Furthermore, the effects of the IgG reactions can become cumulative over time as chronic inflammation contributes to other health concerns and symptoms. IgG allergy testing is a valuable tool when a symptom picture reflects inflammation and is not being resolved by other means.

Testing for IgG food allergies can be done quickly in the clinic with a simple finger prick to obtain a sample of blood. Analysis is done through Rocky Moutain Analytical Laboratories, who provide a detailed report. It is important to consume a wide variety of foods a minimum of 7 days prior to taking this test in order for allergen-antibody complexes to form for the foods being tested.

IgE Reactions 

IgE reactions usually occur quickly following exposure to the offending allergen, thus making it clear and easy to diagnose. Hives on the skin or difficulty breathing after exposure to an allergen are examples. These types of reactions generally involve the respiratory system, skin and digestive tract with obvious symptoms.  

What is the difference between food intolerances and food allergies?

At times, an allergy test might not reflect an immune response to a food that causes a known reaction in an individual. In this case, the results may be due to an intolerance. For example, lactose intolerance is due to a deficiency in the lactase enzyme rather than an allergen-antibody reaction. Low stomach acid or digestive enzymes can also contribute to intolerances.

Management of allergy and intolerances is done through clinical nutrition, supplements, botanical medicine and acupuncture depending on the specific symptoms unique to each individual.
