Dictionary of Allergies .. Open food challenge (OFC)

Both the physician and the patient are aware that the patient is eating the suspected food. The challenge food is not disguised in any way.

For example, a child with a history of egg allergy is given increasing doses of scrambled egg every 30 minutes until a whole egg is ingested. Generally, OFC is used when the skin testing for the suspected food is negative
