Abstract
Skin tests have a central role in the diagnostics of food allergy. Particularly the prick test is established as a routine diagnostic tool. However, instable allergens and the lack of standardized extracts raise problems in the identification of sensitizations to food in suspected food allergy. Therefore, prick to prick tests with native foods are still recommended. The indications and contraindications do not differ with regard to common rules of skin testing in clinical allergology. We recommend a careful and restrictive application of skin tests in patients with a history of severe anaphylaxis to foods.
