- What is the Faecal Calprotectin Test?
- The faecal calprotectin test measures the concentration of calprotectin, a protein released by white blood cells, in the stool.
- It helps to detect inflammation in the intestines, which is a hallmark of Inflammatory Bowel Disease (IBD).
- Why is the Faecal Calprotectin Test Important?
- It is commonly used to differentiate IBD from non-inflammatory conditions like Irritable Bowel Syndrome (IBS).
- High levels of calprotectin in stool indicate active inflammation, which can be due to Crohn’s disease or ulcerative colitis.
- It is a non-invasive test, making it preferable over more invasive procedures like colonoscopy in certain cases.
- How is the Test Conducted?
- The test involves collecting a small sample of stool, usually done at home.
- The stool is then sent to a laboratory where the calprotectin levels are measured.
- Elevated results typically indicate the presence of inflammation in the intestines.
- Interpreting Results:
- Normal levels: A normal calprotectin level generally rules out significant intestinal inflammation.
- Elevated levels: Higher levels suggest active IBD or infection and may require further diagnostic testing or treatment adjustments.
- Monitoring IBD: The test is also useful for monitoring disease activity in people with IBD, helping guide treatment decisions.
- When Should the Test be Used?
- It’s recommended when a patient presents with chronic gastrointestinal symptoms, like abdominal pain, diarrhea, or weight loss, especially when IBD is suspected.
Recommended Tests
- Erythrocyte Sedimentation Rate (ESR): This blood test measures inflammation and is often used alongside the faecal calprotectin test to evaluate the presence of inflammatory conditions like IBD.
- Complete Blood Count (CBC): A CBC test can help detect anemia or infection, both common in patients with IBD, providing additional information on overall health.
