How does it work?

The different allergy tests available can be overwhelming for parents. In our office we perform the “prick method” skin test. This tests for allergic antibodies and is usually performed on the back (but may also be performed on the arms). The skin is pricked with a needle where a drop of allergen has already been placed and noting the development of a positive reaction (which includes a wheel, swelling, or flare in the surrounding area of redness). The results are read at 15 to 20 minutes after the application of the allergen.
