OUTPATIENTS
Outpatients stool samples are tested with a multi-pathogen Nucleic Acid Amplification Test (NAAT) panel that includes C. difficile TOXIN GENE. If this is positive an EIA test for FREE TOXIN is subsequently performed.
Possible results
NAAT toxin gene NEGATIVE - This rules out C. difficile colonization or disease.
INPATIENTS
Inpatient samples are tested for C. difficile using a test for ANTIGEN (GDH) and a test for FREE TOXIN simultaneously.
Possible Results
ANTIGEN negative / FREE TOXIN negative - This rules out C. difficile colonization or disease.
