During testing for suspected celiac disease, what must be done with gluten in the diet until testing is complete?

• A. Gluten must remain in the diet
• B. Gluten should be removed immediately
• C. Gluten should be increased temporarily
• D. Gluten status is irrelevant

Answer: (A)

When testing for suspected celiac disease, gluten should stay in the diet because the autoimmune response and the damage to the intestinal lining are triggered by gluten exposure. Serology tests (like specific antibodies) and biopsy findings reflect what happens when gluten is present. If gluten is removed before testing, antibody levels can fall and the mucosa can heal, leading to false-negative or inconclusive results and delaying diagnosis. Keeping gluten in the diet during evaluation ensures the tests accurately reflect the patient’s true disease state. If a patient has already started a gluten-free diet, clinicians may need to reconsider the testing plan, sometimes by reintroducing gluten to assess the response, to avoid misdiagnosis.
