Outcomes of allergy testing after an emergency department visit for food anaphylaxis

Background Anaphylaxis is a potentially life threatening allergic reaction. Failure to identify the inciting allergen places patients at risk of future life-threatening allergen exposure. Anaphylaxis guidelines recommend that all patients who experience anaphylaxis from an allergen encountered in a non-medical setting carry self injectable epinephrine and follow up with an allergist. Very little data is available on outcomes of allergy follow up after an emergency department (ED) visit for anaphylaxis. The aim of our study was to determine the outcomes of allergy follow up after an ED visit for food anaphylaxis.
