Calprotectin Assay Range

Calprotectin is a heterodimeric calcium binding protein (MRP8/14), which is present in both neutrophils and monocytes. Calprotectin is released from these cell types at sites of active inflammation.

Calprotectin is present in both plasma and faeces, but at 6-fold greater concentrations in the latter. In addition to calprotectin being a highly sensitive and specific marker for gut inflammation, it is also highly stable in faecal samples (up to 7 days when kept at 4C), making this protein a very practical biomarker.
