Interpretive

Reference Range:
 
Less than 0.10 kU(a)/L None detected
F428  0.10 kU(a)/L or greater Primarily associated with local reactions, heat and digestion labile, roasted hazelnuts may be tolerated
F425  0.10 kU(a)/L or greater Associated with local as well as systemic reactions, heat and digestion stable.
F441 and F439  0.10 kU(a)/L or greater Associated with systemic reactions, heat and digestion stable, highly abundant in hazelnuts
 
Use:To distinguish between allergy due to cross-reactivity and primary hazelnut allergy, aid in risk assessment and manage hazelnut allergic patients.
