If your history suggests a possible food allergy, your allergist may recommend an oral food challenge (OFC) to confirm or refute this. OFCs involve eating small and gradually increasing amounts of a food you may be allergic to under observation in a safe, controlled setting. Experts agree that OFCs are essential for the accurate diagnosis of food allergies, as both skin and blood testing have a high rate of false or clinically-irrelevant positive results.

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