IBD: Faecal calprotectin testing--the need for better standardization

Abstract

Measurement of faecal calprotectin concentration is increasingly used to assess disease activity in patients with IBD. Lasson et al. have now demonstrated that calprotectin concentrations in faeces of patients with mild or moderate left-sided or extensive ulcerative colitis vary considerably and have questioned the long-term stability of calprotectin when stored at room temperature.
