Abstract
Peanut allergy (PA) is steadily increasing world-wide (2% in some regions), while self-reported PA prevalence ranges 0-7,2%. Given the PA impact on quality-of-life (QoL), accurate diagnosis is crucial because many sensitized individuals are actually tolerant to peanut. Peanut sensitization established by IgE antibodies (IgE-ab) in blood or skin prick test (SPT) often needs to be confirmed by the “gold standard” DBPCFC, a risky and expensive procedure. PA can be effectively diagnosed using molecular allergology (MA), identifying subjects at risk for PA reactions (IgE-ab to Ara h 1-2-3).
