What is it indicated for?
The C. DIFF QUIK CHEK COMPLETE rM test is a rapid, membrane enzyme immunoassay for the simultaneous detection of Clostridium difficile glutamate dehydrogenase antigen and toxins A and B in a single reaction well. The test detects C. difficile antigen, glutamate dehydrogenase, as a screen for the presence of C. difficile and confirms the presence of toxigenic C. difficile by detecting toxins A and B in fecal specimens from persons suspected of havihg C. difficile disease. 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.
Indications for use as stated in the FDA summary.
