What is it indicated for?
The Great Basin Toxigenic C. difficile Direct Test, performed on the Great Basin PA500 Analyzer, is a qualitative in vitro diagnostic test for the detection of toxigenic Clostridioides difficile in unformed (liquid or soft) stool samples collected from patients suspected of having C. difficile infection (CDI). The automated assay utilizes polymerase chain reaction (PCR) to detect a conserved region of the toxin gene (tcdB) associated with toxin-producing C. difficile.
The Toxigenic C. difficile Direct Test is intended for use as an aid in the diagnosis of CDI in conjunction with clinical and epidemiological risk factors
