A gluten challenge is the period of time when gluten is added back into a person’s diet to assist in the diagnosis of celiac disease. Antibodies take time to build into the blood stream before they can be detected through blood analysis. For a gluten challenge we recommend eating 1/2 slice of bread or a cracker each day for the duration of the challenge.
- Prior to blood testing we recommend 12 weeks of eating gluten.
- Prior to an endoscopic biopsy we recommend 2 weeks of eating gluten.
In the case of a severe reaction to gluten, a medical professional may opt to shorten the 12-week challenge and move immediately to an endoscopic biopsy. May, 2013
