Food Allergies are an irregular response to certain foods activated by your body’s immune system. For people with food allergies, consuming even small amounts of particular foods can cause the body to react to something that is otherwise harmless. Some of our most popular food allergy tests are Gluten, Soy, Chicken, Lactose Tolerance, and Casein. We also offer food sensitivity tests as well. Shop additional Allergy Tests confidentially and order online without insurance or a doctor's note.
