AllergyIntolerance

Allergies and intolerances recorded for the patient.

Includes drug, food, and environmental entries, each with clinical and verification statuses and a criticality. Treat an empty search result as "no allergies recorded", not "no known allergies" — check the record's verification status semantics before displaying safety-critical banners.

Advertises a validated CA Core+ profile.
