The calprotectin test is a valuable diagnostic tool used primarily to assess inflammation in the intestines. It measures the level of calprotectin, a protein released by white blood cells during inflammation. This test is particularly significant for individuals suspected of having inflammatory bowel diseases (IBD) such as Crohn’s disease or ulcerative colitis. By providing insights into the presence and severity of intestinal inflammation, the calprotectin test can help guide treatment decisions and monitor disease activity.
Understanding the Calprotectin Test
What Does the Test Measure?
- The calprotectin test quantifies the concentration of calprotectin in stool samples.
- Elevated levels often indicate inflammation in the gastrointestinal tract, which can be a sign of IBD or other conditions.
- Normal levels typically suggest that inflammation is not present, helping to rule out serious gastrointestinal issues. The test is non-invasive and relatively easy to perform, making it a preferred choice for both patients and healthcare providers. It provides a clearer picture of intestinal health without the need for more invasive procedures like colonoscopy, especially in initial assessments.
Who Should Get Tested?
- Individuals experiencing gastrointestinal symptoms such as chronic diarrhea, abdominal pain, or unexplained weight loss.
- Patients with a family history of IBD or those who have previously been diagnosed and are undergoing monitoring.
- Anyone with symptoms that suggest an inflammatory process in the gut, as determined by their healthcare provider. The calprotectin test is particularly useful for differentiating between IBD and irritable bowel syndrome (IBS), as the latter typically does not cause elevated calprotectin levels. This distinction is crucial for appropriate treatment and management.
How is the Test Conducted?
- A stool sample is collected by the patient, usually at home, and sent to a laboratory for analysis.
- Results are typically available within a few days, providing timely information for both patients and doctors.
- The test is generally safe, with no risks associated with the collection process. In summary, the calprotectin test serves as an essential tool in the diagnosis and management of gastrointestinal inflammation. Its ability to provide quick and reliable results makes it a cornerstone in the evaluation of conditions like IBD, ultimately leading to better patient outcomes.

FAQs About Calprotectin Levels in Stool
1. What is a normal calprotectin level?
A normal fecal calprotectin level is generally below 50 µg/g. This indicates minimal or no inflammation in the gastrointestinal (GI) tract. Individuals with normal levels typically do not have inflammatory bowel disease (IBD) or significant GI conditions.
2. What diseases have high calprotectin?
Elevated calprotectin levels can indicate several conditions, including:
- Inflammatory Bowel Disease (IBD) – Crohn’s disease and ulcerative colitis.
- Gastrointestinal infections – Bacterial or viral infections affecting the intestines.
- Colorectal cancer – In some cases, elevated levels may prompt further testing.
- Diverticulitis – Inflammation of pouches in the colon wall.
- Celiac disease – Chronic inflammation due to gluten sensitivity.
- Use of NSAIDs – Non-steroidal anti-inflammatory drugs like ibuprofen can cause mild inflammation and raise calprotectin levels.
3. What level of calprotectin indicates IBS?
Irritable Bowel Syndrome (IBS) does not typically cause high calprotectin levels. Most people with IBS have levels below 50 µg/g. If calprotectin levels are above 100 µg/g, it may suggest inflammation, pointing more toward conditions like IBD rather than IBS. A doctor may use additional tests to differentiate IBS from inflammatory conditions.
4. Does high calprotectin always mean Crohn’s?
No, a high calprotectin level does not always mean Crohn’s disease. While elevated levels are common in Crohn’s, they can also result from other conditions like infections, NSAID use, or other inflammatory diseases. A confirmed Crohn’s diagnosis requires further testing, such as endoscopy, colonoscopy, and imaging studies.
