One of the questions that crops up in the clinical management of patients suspected of having coeliac disease, is: If my patient has been gluten free, or is going to try an exclusion from gluten containing foods, how long should they be free of gluten before undertaking a gluten challenge test?An article in GUT looks to explain this in some detail [1]

Understanding the risk factors, clinical presentations and diagnostic modalities is necessary to identify and treat patients with this commonly misdiagnosed disorder.
