description: This profile represents the constraints applied to the AllergyIntolerance resource by the PS-CA project. It documents the relevant allergies or intolerances (conditions) for a patient, describing the kind of reaction (e.g. rash, anaphylaxis,..); preferably the agents that cause it; and optionally the criticality and the certainty of the allergy.
