Skin Prick Allergy Test

Picture of a skin prick allergy test

A drop of a solution containing a possible allergen is placed on the skin. Then a series of scratches or needle pricks lets the solution enter the skin. If the skin gets a red, raised itchy area (called a wheal), it usually means that the person is allergic to that allergen.
