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
Non-celiac gluten sensitivity in gluten and gluten-containing cereals (wheat, rye, barley, and their derivatives) may have a role in the development of symptoms. FODMAPs are present in gluten-containing grains and have recently been identified as a possible cause of gastrointestinal symptoms in NCGS patients, but do not justify extra-digestive symptoms. For these reasons, NCGS is a controversial clinical condition and some authors still question it. It has been suggested that "non-celiac wheat sensitivity" is a more appropriate term, without forgetting that other gluten-containing cereals are implicated in the development of symptoms. NCGS is the most common syndrome of gluten-related disorders with prevalence rates
