--although, according to much of the research, the IgG anti-gliadin test is the most sensitive, but least specific, test for gluten problems. People with isolated raised anti-gliadin IgG titres without rasied anti-gliadin igA titres or antitransglutaminase titres are less likely to show frank celiac with villious atrophy and more likely to show gluten sensitivity.

The Gluten file, jcc's compendium of information on all things gluten (which is linked to at the the top of this forum under 'useful websites'), helps to explain this and a lot more (in particular, look for the work of Dr. Hadijvassiliou).
