C. difficile Management
Test Interpretation

Test Interpretation

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.
