Food Sensitivity Testing
Patients tend to think a Food Sensitivity Test and Food Allergy Test are the same thing… with the increasing knowledge in physical symptoms people experience from different foods, many people would like to better understand the true cause, but do not clearly understand the true differences between a food allergy and a food sensitivity.
Let’s take a quick look at what’s actually being tested when a patient has a food allergy and or a food sensitivity. IgA, IgG, and IgE are antibodies within our immune system that are produced in response to foreign invaders such as parasites, bacteria, and viruses, but can also respond to overexposure of certain foods we are sensitive to.
What’s a Food Allergy?
A food allergy is an Immediate reaction to food that is IgE-mediated, which can result in hives, throat swelling and even anaphylaxis (i.e., severe allergic reaction causing airway closure, low blood pressure, and even shock). The most common anaphylactic reactions occur due to certain foods, medications and insect stings.
What’s a Food Sensitivity?
A food sensitivity on the other hand is typically more of a delayed reaction and relates to both IgA and IgG-mediated reactions.
