There are several types of food allergy testing. An experienced allergy physician can help you to determine your exact allergens as well as their severity through any of a series of tests.

IgE Skin Tests are extremely common and relatively painless. You are given a tiny amount of potential allergens through a small prick in your skin to determine whether or not your body produces an allergic reaction. You can see results in about 20 minutes. If you are allergic, that particular spot will swell and possibly itch. These wheals typically disappear within 30 minutes.
Blood tests, known as RAST, provide an alternative to other testing formats that may not work due to existing skin conditions or medication. The results take longer than other tests, however.

It is important to have your allergy testing done at the office of a physician experienced in allergies in order to ensure your safety as well as the most accurate results.
