As of September 2016 the microbiology lab will abandon routine Clostridium difficile PCR testing and adopt the C. diff Quik Chek Complete® EIA test
The C. diff Quik Chek Complete® EIA test utilizes antibodies to detect glutamate dehydrogenase (GDH) (also known as the antigen common to both toxigenic and non-toxigenic C. diff) and Toxins A/B
GDH or Ag will be positive if C. diff (toxigenic or non-toxigenic) is present
Toxin A/B will be positive when toxigenic C. diff is actively producing toxin
General Interpretation of Results:
