Pcr testing for c diff
SpletThe aim of the present study was to evaluate a two-step approach for the diagnosis of CDI. The two-step procedure consisted of GDH-toxin A/B EIA (Enzyme immunoassay targeting enterotoxin A and Cytotoxin B), followed by PCR detecting toxigenic C. difficile. Spletprovide the same diagnostic information regarding C. difficile: a PCR and a toxin result. There is no role for performing both tests simultaneously or performing a C. diff PCR after a positive GI Panel result. These practices do not change management, lead to overutilization of testing resources, and should be avoided.
