Molecular diagnosis of fruit and vegetable allergy

Abstract

Food and vegetable allergy can be acquired both via a direct sensitization over the gastrointestinal tract and via a primary sensitization to pollen or latex. The diagnosis of fruit and vegetable allergy in birch pollen-sensitized patients should not be excluded on a negative IgE testing to extracts. Bet v 1-related allergens are often under-represented in extracts. Few recombinant allergens derived from fruits and vegetables are nowadays commercially available and facilitate diagnosis of fruit and vegetable allergies
