What is an allergy skin prick or scratch test?

Quick easy test. Allergy skin testing using the prick, puncture or formally known as scratch test is the preferred method to assess for food or environmental allergies. It can be accomplished quickly and safely in the allergist's office and the result is known in 20 minutes. If it is positive, the site where the allergen was place will appear and feel like a mosquito bite. Newer skin test devices have less pain.
Allergy test. An allergist will introduce small amounts of specific antigens or substances that can cause allergy through a small needle into the skin. The allergist then looks for a reaction. Typically multiple allergy tests are performed in the same session.
