The allergist will first ask you about your symptoms and medical history. Make sure to tell your allergist if the symptoms are always present or at certain times of the year. Your allergist will perform a skin prick test (SPT) or specific IgE blood test to find out the specific allergen that is causing your symptoms.
During this test, the allergist will insert a small number of different types of allergens after pricking different areas of the skin. Within 15 to 20 minutes, if you have an allergic reaction to any of the substances you will develop swelling, redness, and itchiness at the site.
Your allergist may also perform a blood test. In this test, your allergist will take a blood sample and send it to the laboratory
