Approach to monitoring celiac disease

DGP: deamidated gliadin peptide; DXA: dual-energy x-ray absorptiometry; GFD: gluten-free diet; TTG: tissue transglutaminase.

* TTG and DGP can be used for monitoring celiac disease considering the availability of test at baseline before initiation of the GFD.

¶ Other tests may include complete blood count, alanine aminotransferase, aspartate aminotransferase, vitamins (A, D, E, B12), copper, zinc, folic acid, ferritin, and iron.

Δ Blood tests at follow-up should be individualized to verify correction of laboratory tests that were abnormal at baseline.
