Reagent, prepared from human serum, intended for use as an unassayed precision control for determination of the following autoantibodies: anti-gliadin IgA isotypes Glia IgA ,anti-transglutaminase IgA isotype tTG IgA ,anti-deamidated gliadin peptide IgA isotype DPG IgA .
A material which is used to verify the performance of a number of assays intended to be used for the qualitative and/or quantitative screening for one or multiple antibodies associated with Coeliac disease in a clinical specimen. These antibodies may include autoimmune antibodies directed at gliadin (anti-gliadin IgA or IgG) endomysium (anti-endomysial antibodies), immunoglobulin A (anti-IgA) and/or tissue transglutaminase antibodies (anti-tTG).
