The SNOMED CT concept model for allergy-related conditions has undergone significant changes (see Appendix B for : Historical SNOMED CT content perspective for the history of changes). Currently, SNOMED allergy content is organized under the umbrella of hypersensitivity, which is defined by the World Allergy Organization (WAO) as “objectively reproducible symptoms or signs initiated by exposure to a defined stimulus at a dose tolerated by normal persons”.

Concept models for representative allergic conditions are illustrated below (in the stated view). A similar approach is used to model unspecified hypersensitivity and non-allergic hypersensitivity diseases, propensities, and reactions.
