"The most comprehensive, sensitive and specific test on the market to determine the spectrum of wheat and gluten related disorders". This test measures your immune reaction to wheat, gluten, gliadins and many other proteins that gluten breaks down into, as well as non-gluten wheat proteins that may be present in "gluten free" grains. Yes, this test can tell us why you tested negative for gluten sensitivity in the past but still seem to have problems! Also tested is intestinal permeability, with different antibodies being correlated with autoimmune reactions to gut, skin, or brain. This is truly a remarkable test panel!
