Skin test

Skin tests are the most commonly used specific tests and include patching, scratching, picking, and intradermal injections. Picking and intradermal tests are the most commonly used clinically, such as negative picking tests; can be reviewed for intradermal tests. Method and principle: After specific patients are exposed to allergens, specific IgE can be induced. This antibody adheres to IgE receptors on the surface of mast cells in the skin or submucosa. It forms when it meets allergens that re-enter the body The bridge between 1 allergen and 2 IgE antibodies causes a series of biochemical processes in mast cells, releases allergic mediators, and locally produces wind masses, redness or itching.
