Gluten intolerance? GlutenCHECK is a rapid test for home use to detect the presence of IgA tissue transglutaminase antibodies (tTG) in whole blood. GlutenCHECK is suitable for the initial diagnosis of gluten intolerance as well as for monitoring therapy. The level of a-tTG-IgA antibodies should drop when gluten is removed from the diet. After 6 months on a gluten-free diet, antibodies often become undetectable. The diagnosis must be confirmed by a healthcare professional along with additional recommendations for maintaining a gluten-free diet. Each kit contains everything needed to perform the test: test cassette, instructions, bottle of sample dilution buffer solution, 1 automatic sterile lancet for convenient blood sampling, glass capillary tube, pipette, alcohol pad and plaster. Results can be read within 10 minutes. Background Gluten intolerance (celiac disease), known as sprue in adults, is an autoimmune disorder of the small intestine where the immune system attacks the body's own tissues. Common symptoms of gluten intolerance include bloating and diarrhea, caused by a reaction to the gluten protein found in many foods. Weight loss, malnutrition and skin disorders can also be indications of gluten intolerance.
