Test Overview & Methodology
The C. difficile Toxin A & B and GDH Stool Test rapidly detects Clostridioides difficile toxins and glutamate dehydrogenase antigen, the gold‑standard screening for antibiotic‑associated diarrhea. Results guide precise antibiotic stewardship and recurrence management in UAE healthcare settings. The diagnostic algorithm uses immunochromatography for GDH, enzyme immunoassay for Toxin A/B, and reflex Xpert® C. difficile PCR for confirmation.

Physician Insight & Safety Protocols
“Clinical correlation is essential; a positive result must be interpreted alongside symptoms, recent antibiotic use, and hospitalization history to avoid overdiagnosis. Always consider specimen quality and potential colonization in asymptomatic patients. This test empowers UAE clinicians to differentiate true infection from carriage and initiate timely treatment.”
