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 (GDH), in fecal specimens from persons suspected of having C. difficile disease.
The test does not distinguish toxigenic from nontoxigenic strains of C. difficile.
The device contains a Reaction Window with two stripes.
One stripe is a test line specific for GDH, and the other is the control line.
