Fecal Calprotectin

Meaning

Fecal Calprotectin is a clinically valuable and non-invasive biomarker measured in a stool sample, representing a calcium-binding protein predominantly released by neutrophils, a type of white blood cell, into the intestinal lumen. Elevated concentrations of this protein serve as a highly sensitive, objective indicator of active inflammatory processes occurring within the gastrointestinal tract, often correlating with mucosal damage or inflammatory bowel conditions. Monitoring this marker allows for a quantifiable, real-time assessment of intestinal inflammatory status, which is deeply relevant to overall systemic health and the gut-hormone axis.
