What is it indicated for?

The ARIES C. difficile Assay is a real-time polymerase chain reaction (PCR) based qualitative in vitro diagnostic test for the direct detection of toxigenic Clostridium difficile (C. difficile) nucleic acid in unpreserved, unformed (liquid or soft) stool specimens obtained from patients suspected of having Clostridium difficile infection (CDI). The test targets the C. difficile toxin A gene (tcdA) and toxin B gene (tcdB) and is indicated for use as an aid in the diagnosis of C. difficile infection (CDI).

The ARIES C. difficile Assay is indicated for use with ARIES Systems.

Indications for use as stated in the FDA summary.
