Overview
VIDAS® C. difficile GDH is a qualitative test that detects the C. difficile antigen, glutamate dehydrogenase (GDH), in stool specimens to screen patients suspected of having C. difficile infection. It is used in conjunction with VIDAS® C. difficile Toxin A&B as part of a two-step algorithm.
VIDAS® C. difficile immunoassays are adapted to current diagnosis guidelines with:
- VIDAS® GDH highly sensitive test for the screening
- VIDAS® CDAB highly specific test for the toxin detection
C. difficile Infection Management
Clostridioides difficile (C. difficile) is one of the most challenging Healthcare Associated Infections (HAI)1. It is usually contracted in the healthcare setting and is connected to antibiotic treatment. C. difficile infection (CDI) generates costly treatment, patient isolation, and longer hospital stays1.
The rise of Community Acquired Infections is of concern and now accounts for 35-48% of CDI diagnosis in the United States2. During a point-prevalence study in Europe, the CDI positivity was found to be at 1.3% in community samples, and half of community CDI cases were undetected because of the absence of clinical suspicion, representing 3 times more undiagnosed adults in the community compared with hospitals2.
Continued appropriate infection control, antibiotic use, and diagnostic testing are important in decreasing C. difficile cases3.
Greater Clinical Value for Clinicians
The VIDAS® C. difficile panel helps improve patient management with actionable results based on excellent clinical performance:
