IgE, IgG4 and IgA specific to Bet v 1‐related food allergens do not predict oral allergy syndrome

Abstract

Measurements of allergen-specific immunoglobulins are not suitable for diagnosing Bet v 1-mediated plant food allergy to hazelnut and Rosaceae fruits. In contrast, IgE and IgA to the distantly related allergen Api g 1 correlate with allergy to celeriac.
