How we perform gluten challenge to those with suspected gluten-related disorders who are already on a gluten-free diet? What is common food to take? How much amount and duration is needed to see the response (building antibodies including IgA-transglutaminase, IgA-endomysial, anti-Deamidated gliadin and villous change)?
Is it advisable to perform it at a PCP clinic if patient's symptom is mild and only serologic tests are planned?
