A skin prick test is a common method used to identify allergies. During the test, a healthcare professional places small amounts of allergens, such as pollen or pet dander, on the skin's surface. They then use a tiny needle to prick the skin, allowing the allergens to enter just below the surface. After about 15 to 20 minutes, the skin is examined for reactions. A raised, red bump indicates an allergy to that specific substance. Skin prick tests are quick, generally safe, and can help guide treatment options for individuals with allergies.
