Calprotectin
Diagnostic Solutions LaboratoryCatalog information reviewed: August 24, 2026 by the Sunridge Medical clinical team.
What this laboratory test evaluates
Fecal calprotectin has been shown to increase at a faster rate than serum calprotectin suggesting that fecal calprotectin quantification is a significant biomarker for early stage intestinal mucosal inflammation. In addition, calprotectin is highly resistant to degradation by gastric proteases making it an ideal fecal biomarker for non-invasive detection of intestinal inflammation.
A wide variety of conditions can result in increased neutrophils present in the GI tract including:
• Inflammatory Bowel Disease (IBD)
• Crohn’s Disease (CD)
• Food/protein sensitivities
• Ulcerative Colitis (UC)
• Infectious (pro-inflammatory) organisms
Additional test information
Calprotectin is a 36 kDa heterodimeric calcium bind protein that comprises approximately 60% of the cytosolic proteins present in inflammatory cells. Therefore, during intestinal inflammation, calprotectin quantification can be used to measure the level of neutrophils present in the intestinal lumen.
