Calprotectin
Background:
To rule-out inflammatory bowel disease (IBD) in patients where irritable bowel syndrome is suspected.
For GPs, please see Faecal Calprotectin - local guideline for primary care for further information.
For information on how to collect a stool sample, please see NHS Instructions for collecting a stool sample
At least a pea-sized amount of faeces is required for analysis.
Key points to consider:
- Calprotectin testing is not appropriate in patients > 45 years, unless monitoring patients known to have IBD.
- Test should not be requested in patients with red flag indicators or in those with known infectious diarrhoea.
- Visibly bloody stool samples will not be analysed; patient should be urgently referred for further investigation.
- NSAIDS may causes a false positive result.
Serial testing is generally not appropriate. All requests made within 6 months of a previous request will be reviewed by the Duty Biochemist, and may be rejected if considered unnecessary.
