Calprotectin is a calcium-containing protein that makes up 5% of the total protein and 60% of the cytosolic protein of neutrophils. It has bacteriostatic and fungistatic properties and is found in feces at levels six times higher than that in plasma. That fecal biomarker is useful to assess the activity of inflammatory bowel disease (IBD). IBD includes Crohn's Disease (CD) and Ulcerative Colitis (UC) and are associated with elevated neutrophils.

This fecal calprotectin assay is useful in differentiating organic (IBD) from functional gastrointestinal disease (IBS: Intestinal Bowel Syndrome). It is a simple, non-invasive biomarker that is especially useful in children, who may require general anesthesia for colonoscopy. And this fecal calprotectin detection can predict relapse.

Intended Use of Calprotectin Antibody Rapid Test

Calprotectin Rapid Test Cassette (Faeces) is a rapid chromatographic immunoassay for the qualitative detection of Calprotectin in human faeces specimen which might be useful for the diagnosis of inflammatory gastrointestinal disorders.

What Is Fecal Calprotectin (Calprosmart) Home Test Kit

Calprotectin is a 24 kDa dimer of calcium binding proteins S100A8 and S100A9. The complex accounts for up to 60% of the soluble protein content of the neutrophil cytosol. Calprotectin becomes available in the intestinal lumen via leukocyte shedding, active secretion, cell disturbance, and cell death. This results in elevated faecal calprotectin levels, which can be detected in the stool.

Elevated faecal calprotectin levels therefore indicate migration of neutrophils into the intestinal mucosa, which occurs during intestinal inflammation.[4] Faecal calprotectin has been used to detect intestinal inflammation and can serve as a marker for inflammatory bowel diseases. Calprotectin is useful as a marker, as it is resistant to enzymatic degradation, and can be easily measured in faeces

What Is Calprotectin Test

The Calprotectin Test is a medical diagnostic test used to measure the levels of calprotectin in the stool. Calprotectin is a protein found in the white blood cells, and it is released during inflammation in the body, particularly in the gastrointestinal (GI) tract. The Calprotectin Test is used to detect inflammation in the GI tract, helping to identify conditions such as inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), and other conditions that may be causing GI symptoms. The test is noninvasive and can be performed using a stool sample, making it a convenient solution for early detection and diagnosis of GI conditions. Elevated levels of calprotectin in the stool can indicate that inflammation is present in the GI tract, and further testing and evaluation may be necessary to identify the underlying condition and develop a treatment plan.

Calprotectin Test Results

Calprotectin test results can either be positive or negative. A positive test result indicating elevated levels of calprotectin in the stool, which may suggest the presence of inflammation in the gastrointestinal tract. A normal or negative test result indicating that the levels of calprotectin in the stool are within the normal range, which may suggest that there is no active inflammation in the gastrointestinal tract.
