Hi was wondering if anyone had done the saliva test for Gliadin for celiac disease and how accurate is the test? I returned home with a positive test of 19 from the saliva test done by Diagnos-Techs, Inc. which my naturopath ordered. Borderline was 13-15 and positive is >15. She did send me today for blood test too. I was just having some anxiety as it is the weekend and this test read positive. Anyone know is this is pretty accurate testing??
