C. difficile Infection (CDI)

  • C. difficile toxin assay

  • Routine labs, especially renal function

  • Imaging (plain film abdo, CT abdo) should be considered in patients with abdominal tenderness, as well as those with complicated or severe disease, to assess for ileus, perforation, megacolon, bowel wall thickening

  • Endoscopy (signmoidoscopy or colonoscopy) to assess for pseudomembranous colitis especially helpful when diagnosis uncertain and to assess for alternate causes with optimal sample collection
