A prospective evaluation of the predictive value of faecal calprotectin in quiescent Crohn's disease.

Background: Faecal calprotectin (FC) is a non-invasive marker of gastrointestinal inflammation.

Aim: To determine whether higher FC levels in individuals with quiescent Crohn's disease are associated with clinical relapse over the ensuing 12 months.

Methods: A single centre prospective study was undertaken in Crohn's disease patients in clinical remission.
