Clostridioides difficile Culture, Varies
Use
Providing an isolate suitable for antimicrobial susceptibility testing. Culture provides definitive evidence of the presence of the bacterium Clostridioides difficile in feces, which can lead to antibiotic-associated diarrhea and pseudomembranous colitis. Overgrowth of toxin-producing C. difficile leads to the production of toxins and diarrhea, with risk factors including recent use of antibiotics and hospitalization. C. difficile infection is the most common cause of diarrhea in hospitalized patients and may lead to serious complications if not managed properly.
Special Instructions
Not provided.
Limitations
This test does not differentiate between toxin-producing and non-toxin-producing strains of C. difficile. Testing of asymptomatic patients or for test of cure is not recommended. Testing formed feces is generally not clinically indicated. Isolation of C. difficile from colostomy, ileostomy, or colonoscopically collected specimens has not been validated. Testing of colostomy, ileostomy, or colonoscopically collected specimens has not been optimized. Performance characteristics are specific to this methodology and laboratory conditions.
