The calprotectin stool test is a non-invasive diagnostic tool that measures calprotectin, a protein released by white blood cells during intestinal inflammation, helping identify bowel inflammation and differentiate between conditions like IBD and IBS.
What is a Calprotectin Stool Test?
A calprotectin stool test is a non-invasive diagnostic tool that measures the level of calprotectin, a protein found in stool, to assess intestinal inflammation. Calprotectin is released by neutrophils, a type of white blood cell, during inflammation in the gastrointestinal tract; Elevated levels of calprotectin in the stool are associated with inflammatory bowel disease (IBD), while normal or low levels often indicate non-inflammatory conditions like irritable bowel syndrome (IBS). This test is highly sensitive and helps differentiate between various gastrointestinal disorders by identifying the presence of inflammation.
Why is the Calprotectin Stool Test Performed?
The calprotectin stool test is primarily performed to assess intestinal inflammation and differentiate between inflammatory and non-inflammatory bowel conditions. It is commonly used to diagnose and monitor inflammatory bowel disease (IBD), such as Crohn’s disease and ulcerative colitis. The test helps identify inflammation by detecting elevated calprotectin levels, which are associated with the presence of neutrophils in the stool. It is also used to distinguish IBD from irritable bowel syndrome (IBS), which does not involve inflammation. Additionally, the test can monitor disease activity and treatment response in patients already diagnosed with IBD, making it a valuable tool in managing gastrointestinal health.
