Skin test are used for which hypersensitivity reactions?
Type I hypersensitivity reaction is IgE dependent. When a small shocking dose of an antigen is administered intradermally to a sensitised host, there will be a local wheal and flare response. This is cutaneous anaphylaxis. Cutaneous anaphylaxis ( skin test for typ I hypersensitivity ), is useful in testing for hypersensitivity and in identifying the allergen responsible in atopic diseases.
