Supervised Food Challenges
A carefully structured test in which your child eats gradually increasing amounts of a food under medical supervision, to determine whether a clinical allergy is present.
A supervised food challenge (oral food challenge, OFC) is the most accurate method for diagnosing food allergy. It involves your child eating the suspect food in small, gradually increasing amounts under direct medical supervision.
Challenges are performed at a hospital clinic with emergency anaphylaxis medication immediately available.
What to expect
The food is divided into small portions, given at 15–30 minute intervals. If no reaction occurs after all portions are eaten and an observation period has passed, the challenge is considered negative.
If a reaction occurs at any dose, the challenge is stopped and treatment is given immediately.
If your child is having a severe allergic reaction, call 999 immediately or go to your nearest A&E. Do not wait. Always carry prescribed emergency medication as directed by your doctor.
Frequently asked questions
All challenges are performed in a clinical setting with emergency anaphylaxis medication immediately available and trained staff present. The dose is increased gradually; the challenge is stopped immediately if any reaction occurs.
Previous allergy tests or a past reaction may not give a clear picture of whether your child is still allergic. A challenge is the most accurate way to find out.
