Exams and Tests

Generally a food allergy is identified by signs and symptoms. Medical professionals are trained to recognize hives, swelling patterns, rashes, and other symptoms associated with allergic reactions.

You will be asked questions about your medical history and possible triggers of the reaction.

Blood tests and other tests are needed only under very unusual circumstances, such as anaphylaxis.

Some people can pinpoint which food caused the allergic reaction, especially if the reaction occurs within minutes of consuming a particular food. Many others will need to see an allergist for special testing to determine the exact food that is responsible.
