TTG antibodies diagnosis
This is a pretty good article that explains the December 2010 research on people with positive blood tTG or EMA blood tests and negative or Marsh 1 biopsy and its implications. Basically, because people with positive bloodwork and negative biopsy have the same metabolic markers as celiacs with full villous atrophy. The researchers recommend a gluten-free diet if you're positive on tTG or EMA, even if your biopsy is completely normal.

In the paper it explains the potential celiacs as: "Patients with potential celiac disease were all positive for anti-tissue transglutaminase antibodies (tTGA); all but one were also EmA positive; histological examination revealed an apparently normal mucosa (Marsh 0) in 9 subjects, just an increase in intraepithelial lymphocytes (Marsh 1) in 12 and increased intraepithelial lymphocytes coupled with crypt hyperplasia (Marsh 2) in 8 patients."
