The C. DIFF QUIK CHEK test is a rapid membrane enzyme immunoassay for use as a screening test to detect Clostridium difficile antigen, glutamate dehydrogenase, in fecal specimens from persons suspected of having C. difficile disease. The test does not distinguish toxigenic from nontoxigenic strains of C. difficile. With the use of additional tests that detect C. difficile toxins, the test is to be used as an aid in the diagnosis of C. difficile disease. As with other C. difficile tests, results should be considered in conjunction with the patient history.
A collection of reagents and other associated materials intended to be used for the qualitative and/or quantitative detection of antigens from Clostridium difficile bacteria [e.g., glutamate dehydrogenase antigen (GDA), toxin A and/or toxin B] in a clinical specimen, using an enzyme immunoassay (EIA) method.
