Oral Food Challenges (OFC)

If your history suggests a possible food allergy, your allergist may wish to perform an oral food challenge (OFC) to confirm or refute this.

OFC involve eating small and then increasing amounts of a food you may be allergic to under observation in a safe, controlled setting. Experts agree that OFC are essential for the accurate diagnosis of food allergy, as both skin and blood testing have an unacceptably high rate of false or clinically-irrelevant positive results.

OFC carry a risk of reaction, including anaphylaxis, however the Snö team of allergists and nurses have extensive training and experience with food challenges, and will only recommend this procedure when appropriate or necessary for your care.
