For clients who have had a previous anaphylactic reaction, the Regulation requires registered nurses to obtain a client-specific order from a listed health professional before they carry out allergy challenge testing by any method.
For clients who have no history of anaphylaxis, registered nurses require a client-specific order from a listed health professional to carry out allergy challenge testing and desensitizing treatment that involves the use of injection, scratch tests or inhalation. Other forms of challenge testing and desensitizing treatment (e.g., elimination and reintroduction of specific foods into the diet) may be done within autonomous scope of practice and therefore without a client-specific order from a listed health professional for clients who have no history of anaphylaxis.
