Frequently Asked Questions


How often should follow-up testing occur?

New celiacs should receive follow-up testing twice in the first year after their diagnosis. The first appointment should occur 3-6 months after the diagnosis, and the second should occur after 1 year on a gluten-free diet. After that, a celiac should receive follow-up testing on a yearly basis. We recommend checking both tTG and DGP (Deamidated gliadin peptides) at each screening. February, 2013
