Are raised DGP-IgG levels an early sign of celiac disease?

Elevated DGP antibodies are often seen in patients with celiac disease on a gluten-containing diet. They appear to have exactly the same value of the more established tTG-IgA antibody test, and offer no advantage over tTG. However, it appears that in very young children (i.e., in the first two years of life) DGP do provide a better test for celiac disease.
