Hypersensitivity encompasses both allergy and non-allergic hypersensitivity. The top-level organizing nodes representing hypersensitivity, allergy, and non-allergic hypersensitivity are referred to as conditions (representing disease states), dispositions (propensities to develop a reaction), and processes (pathological processes underlying the reactions). The disjunctive nature of these conditions is modeled using general concept inclusions (GCIs). Hypersensitivity conditions, including allergy and non-allergic hypersensitivity, are defined in terms of a pathologic process relationship to specific processes in the qualifier value hierarchy.
