About C. difficile Toxin A

This marker detects the gene responsible for producing toxin A in Clostridioides difficile strains. Toxin A damages the intestinal lining and contributes to inflammation, diarrhea, and abdominal pain when actively expressed. Many people carry C. difficile without symptoms, particularly after antibiotic use, but toxin gene presence increases the risk of symptomatic disease. Because this test detects genetic potential rather than the toxin itself, results must be interpreted alongside symptoms and other inflammatory markers. Elevated levels raise concern for active or emerging C. difficile–associated disease.
