The ability of an allergen to invoke an allergic response, despite no prior exposure. Allergens that are derived from related species have protein similarities and can thus cross-stimulate an allergic response. Cross-reactivity may be utilized to limit allergen selection for allergy immunotherapy formulation. The degree of cross-reactivity varies by allergen-type (e.g., grass, tree, weed).
