Anti-gliadin antibodies and wheat-dependent exercise-induced anaphylaxis. The target of the most allergenic antibodies is ω-5 gliadin, which is encoded by the Gli-1B gene found on the B haplome ("Aegilops speltoides" derived) of wheat. What is the relationship of gluten and anti-gliadin antibodies?. In gluten-sensitive individuals AGA testing is a routinely used blood test for possible presence of coeliac disease, allergies or idiopathic phenomena. The measurement of AGA is done with ELISA or radioimmunoassay. Such tests measure the level of AGA relative to a standard, such as a level of 10 = point which 85% of normal population falls below. Greater than 10
Gluten-free diet Manufacturing Practices and allergen control measures adopted are not sufficient to prevent the presence of accidental trace amounts. When a product contains the warning of cross-contamination with wheat, rye, barley, oats and their hybridised strains, the warning "contains gluten" is mandatory. The law does not establish a gluten threshold for the declaration of its absence. Health Canada considers that foods containing levels of gluten not exceeding 20 ppm as a result of contamination, meet the health and safety intent of section B.24.018 of the Food and Drug Regulations when a gluten-free claim is made. Any intentionally added gluten, even at
