If you’re sensitive to an allergen, with the prick or scratch test and intradermal test, a small, red bump appears on the skin where that allergen was placed, and this area may itch. The larger the bump, the more sensitive you may be to it. These results are called positive skin tests and mean that you may be allergic to the allergen tested.

Even if a skin test shows that you’re allergic to something, you may not react to it when you’re exposed to it later. Your allergist will review your medical history and skin test results to help find out what you’re allergic to.
