The Clostridium difficile Rapid Test Cassette is a rapid chromatographic immunoassay for the qualitative detection of Clostridium difficile GDH in the human feces specimen. This is a ready-to-use test that is based on the use of a membrane technology with colloidal gold. A nitrocellulose membrane is sensitized with antibody directed against Clostridium difficile antigen (GDH). The test’s specificity is ensured by an antibody specific to the Clostridium difficile GDH that is conjugated to the colloidal gold. This conjugate is dried on polyester.
