Allergy Skin Test: A test done to identify the allergy-causing substances for your asthma by exposing your skin to suspected allergens. These tests are most reliable for diagnosing allergies to airborne substances, such as pollen, pet dander and dust mites. The test is done by applying a diluted allergen by pricking/puncturing your skin using a small, disposable plastic device.

• Skin testing is also done to diagnose food allergies.
