- Simplified laboratory workflow
- Just one step from sample collection to analysis
- No contamination risk in the laboratory
- Fast and fully automated quantitative immunoassay
Calprotectin is a protein mainly found in the cytoplasm of neutrophilic granulocytes. In cases of gastrointestinal (GI) inflammation, neutrophils migrate through the intestinal wall and calprotectin is released due to degranulation. It accumulates in the faeces and is excreted from the body. The concentration of calprotectin directly correlates with the number of neutrophils in the intestinal lumen, making it an ideal biomarker for GI inflammation.
The determination of faecal calprotectin (fCal) is a non-invasive option to assess localised inflammation. Being highly sensitive for the detection of GI inflammation, it helps in the differential diagnosis of inflammatory bowel diseases (IBD) and irritable bowel syndrome (IBS). The biomarker fCAL outperforms general inflammation markers such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) since it is more sensitive and more specific.
CALiaGold is the complete solution for the automated quantitative determination of calprotectin in human faeces. The particle-enhanced turbidimetric immunoassay (PETIA) is based on the agglutination reaction between latex particles coated with antibody and the antigen in solution. It can be run, along with the FOB Gold test, on your dedicated faecal analyser (SENTiFIT 270 Analyser or SENTiFOB Analyser).
The CALiaGold system comprises a tube for sample collection and a next-generation immunological latex reagent for the detection of calprotectin. CALiaGold brings true convenience to patients, clinicians, and laboratory professionals.

Differential diagnosis of IBD and IBS
- Negative fCAL: low probability of having bowel inflammation (high negative predictive value, NPV), excludes IBD as a diagnosis.
- Elevated fCAL: consistent with the presence of GI inflammation, needs further investigation with endoscopy and histology. No single test is specific enough to diagnose or rule out IBD.
- Normalisation of fCAL levels can be an indicator of effective treatment and achievement of mucosal healing.
- Rising fCAL can predict an imminent clinical relapse of IBD, allowing prompt initiation of treatment.
- can be effective for the management of colonoscopy resources,
- demonstrates to be a non-invasive and accurate assay for monitoring disease activity and response to treatment, and
- can be a prognostic tool for clinical relapses.
