allergy skin test

allergy skin test

a skin test used to detect allergic reactions. Properly performed, it is considered the most convenient and least expensive test for detecting such reactions. The test involves injecting or topically scratching an allergen into the skin and then evaluating the wheal (swelling) and flare (redness) responses that follow. Positive reactions usually occur within 20 minutes.
