Abstract

Abstract : Abstract: Consideration of contact allergen concomitant reactivity, which encompasses cross-reactors, co-reactors, and pseudo cross-reactors, is an important aspect of patient care, yet information on how these terms are differentiated and used in clinical practice is lacking. In this review, we provide definitions of cross-reactors, coreactors, and pseudo cross-reactors and discuss the utility of the American Contact Dermatitis Society Contact Allergen Management Program database cross-reactor groupings. We also discuss limitations to the current categorization of cross-reactivity and recommend incorporating new terms, including "apparent cross-reactor" and "derivative cross-reactor, " when classifying cross-reactors.
