Anti-gliadin antibodies is also found in a number of patients who are not enteropathic. Some of these patients may have neuropathies that respond favorably to a gluten elimination diet. This is referred to as gluten-sensitive idiopathic neuropathy. Clinically these antibodies and IgG antibodies to gliadin are abbreviated as AGA. The IgG antibody is similar to AGA IgA, but is found at higher levels in patients with the IgA-less phenotype. It is also associated with coeliac disease and non-celiac gluten sensitivity. Anti-gliadin antibodies are frequently found with anti-transglutaminase antibodies. The IgE antibodies are more typically found in allergy-related conditions such as urticaria, asthma,
Anti-gliadin antibodies This antibody is a recommended testing protocol in a proposed revision of the Codex Alimentarius. The new standards came about in part because of new sensitive and specific testing procedures. These procedures are capable of detecting wheat or multiple cereals at concentrations as low as 1 part per million (PPM or 1 mg/kg). A new barley-sensitive ELISA called the R5 sandwich assay does not detect gluten in any of 25 pure oat varieties, but it does detect barley, wheat and rye. Anti-gliadin antibodies Anti-gliadin antibodies are produced in response to gliadin, a prolamin found in wheat. In bread wheat it
