A faecal calprotectin test is useful to rule out inflammatory bowel disease (IBD) in general practice patients, Australian gastroenterologists say.

Their meta-analysis of 18 studies found that the stool test had a negative predictive value of 100% for organic gastrointestinal disorders, such as ulcerative colitis and Crohn’s disease, as diagnosed with colonoscopy or imaging.
