GlutenCHECK is a rapid test for use at home to detect the presence of IgA tissue transglutaminase antibodies (tTG) in whole blood.
GlutenCHECK is suitable for both, an initial diagnosis of gluten intolerance as well as a therapy follow-up. a-tTG-IgA antibody level should fall when gluten is removed from the diet. After 6 months on gluten-free diet the antibodies will often become undetectable. The diagnosis must be confirmed by the physician with further recommendation to maintain a gluten-free diet.
