--and JCC, the Most Exalted Mistress of Gluten Wisdom, came back with a post referencing the original article. Excellent reading, especially about the newer classes of anti-glidain and anti-tranglutaminase antibodies that can be tested for, and which may have more predictive value and clinical correlation than the traditional anti-gliadin/anti-transglutaminase assays (though the tests are not widely available yet).

And the article abstract:

JCC seems to have hooked into the actual article in the Lancet--I'm going to try to get it myself, to add to my database (though I haven't checked the Gluten File yet--JCC may have already linked to it).
