The skin prick test is carried out to assess immediate allergic reactions to various substances and is commonly performed to identify allergies to pollen, dust, dander and other foods. This test is usually performed on the forearm, where small marks can be drawn to identify each test antigen.
A solution containing each allergen is dropped next to its identification mark on the forearm.
A lancet is then used to make tiny pricks into the skin at each drop site, allowing the allergen to enter the skin. If you are allergic to a substance, a small red bump will appear on the skin at the marked site, indicating an allergic reaction.
