<<Disclaimer: Verify this information before applying it to your situation.>> On August 17, Markus Dielzig mentioned that his gliadin anti-body tests still showed him to be "gluten free". Judging by technical literature available from Eurospital on their "alpha gliatest", the anti-gliadin tests may only be sensitive to wheat glutens, indeed only the so-called alpha fraction of that gluten. Beer is more likely to have barley and may not be picked up by just this test. Markus, did you have any of the other anti-body tests done at the same time? The reticulin and endosymial anti-body tests may still detect intestinal damage from any of the toxic grain proteins. Can someone understanding these tests better than I comment on this? In any case, it would be helpful to have statements on the sensitivity (or lack therof) of all four blood anti-body tests and the food testing assays all in one place.
