A skin test in which a small scratch is made on the skin of the forearm by a small needle wherein a substance is placed to determine the body\u2019s reaction to the substance.<\/p>\n
A test for allergy, in which a small amount of a substance is placed on a lightly scratched area of skin to see if a reaction occurs.<\/p>\n
Skin test for identifying an allergen. A small amount of a solution containing a suspected allergen is placed on a scratched skin area; if redness and wheal formation develop, allergy to that particular substance is demonstrated.<\/p>\n
An approach to allergy testing performed to identify the allergen that produces symptoms in an affected person. Scratch tests are also called skin prick testing and involve introducing a drop of allergen extract into the skin using a small sharp instrument that causes a small break in the skin.<\/p>\n
Placement of an appropriate dilution of a test material suspected of being an allergen in a lightly scratched area of the skin. If the material is an allergen, a wheal will develop within 15 min. The scratch test is used to detect IgE antibody responses, (e.g., in patients with a history of allergy to penicillin).<\/p>\n
