After going gluten-free, can a positive tTG mean anything other than gluten present in my diet?

tTG normalizes slowly when on a strict gluten-free diet. This process may take years if the starting level is very high. If tTG is still high after a long time, aside from gluten sneaking into one’s diet, this may simply mean, especially with low titers, that it’s falsely elevated—common in patients who have other autoimmune conditions, such as chronic liver disease, Type 1 Diabetes, Crohn’s Disease or thyroiditis.
