Food Diary:

 If you think you have a soy allergy keep a diary of the foods you are eating and what signs and symptoms you are experiencing after eating those foods.

Elimination Diet: Remove soy and soy products from your diet for 2-3 weeks.  After 2-3 weeks gradually reintroduce soy products into your diet and see how your body reacts. You can use as a guide for ingredients to avoid or substitutions. If your symptoms are relieved during the time the food is eliminated, you may be allergic to that food. See your doctor for proper diagnosis.

Skin Test: See your doctor or an allergist and get a test.  Your doctor can perform a skin test. A tiny amount of food that can possibly cause an allergy is applied to your skin, and then your skin is pricked to allow that amount of food to get below the skin’s surface to see if you have a reaction. If you are allergic a rash may develop or another type of reaction can occur on the area that the food was applied. 

Blood Test: A blood test, also called a RAST (radioallergosorbent test) can determine the amount of immunoglobulin E (IgE) antibodies in your blood. Your blood is sent to a lab where they test foods with your blood to see if a particular protein in that food causes high amounts of IgE in your blood. If you have high amounts of IgE then you are allergic to that food.
