The dedicio® H. pylori Antigen Rapid Test Device (Feces) is a rapid visual immunoassay for the qualitative presumptive detection of Helicobacter pylori antigens in human fecal specimens. This kit is intended to be used as an aid in the diagnosis of H. pylori infection.
The dedicio® H. pylori Antigen Rapid Test Device (Feces) has been designed to detect Helicobacter pylori through visual interpretation of color development in the internal strip. The membrane was immobilized with anti-H. pylori antibodies on the test region. During the test, the specimen is allowed to react with colored anti-H. pylori antibodies colloidal gold conjugates, which were precoated on the sample pad of the test. The mixture then moves on the membrane by a capillary action, and interact with reagents on the membrane. If there are enough H. pylori antigens in specimens, a colored band will form at the test region of the membrane. Presence of this colored band indicates a positive result, while its absence indicates a negative result. Appearance of a colored band at the control region serves as a procedural control. This indicates that proper volume of specimen has been added and membrane wicking has occurred.
