Calprotectin is a protein in cells involved in inflammation, found abundantly in neutrophils. Diseases like Crohn’s disease, ulcerative colitis, and cancer cause higher faecal calprotectin excretion, but not in patients with Irritable Bowel Syndrome (IBS).
Fecal Calprotectin Test (FCT) is an enzyme immunoassay intended for the quantitative assessment of calprotectin. It is a cost-effective, non-invasive, and sensitive biomarker to screen patients for intestinal inflammation.
Higher calprotectin concentration in feces indicates Inflammatory Bowel Disease (IBD) and has proven to be
a better disease activity marker on tissue biopsy than blood test markers of inflammation (e.g. white blood
cell count, ESR, and CRP).
INTERPRETATION
- Calprotectin concentrations of 50.0 mcg/g or lower is NEGATIVEThis is not suggestive of an active inflammatory process within the gastrointestinal system. For patients experiencing gastrointestinal symptoms, consider further evaluation for functional gastrointestinal disorders.
- Calprotectin concentrations between 50.0 to 150.0 mcg/g is MODERATELY ELEVATEDThis may be associated with organic intestinal disease but should be interpreted in line with clinical assessment. For patients with clinical symptoms, retesting in 4 to 6 weeks may be indicated.
- Calprotectin concentrations of 150.1 mcg/g or higher is POSITIVEThis suggests active inflammatory process within the gastrointestinal system. Further diagnosis is advised to determine the etiology of the inflammation.
CAUTION
- Normal fecal calprotectin DO NOT exclude the possibility of IBD, and elevated levels is NOT an outright confirmation. IBD Diagnosis should include clinical evaluation and other diagnostic modalities.
- Borderline results in fecal calprotectin may be observed in patients taking non-steroidal anti-inflammatory drugs (NSAID), aspirin, or proton-pump inhibitors.
- Increased fecal calprotectin may also be observed in other diseases like neutrophilic inflammation of the GI system, including celiac disease, gastrointestinal infection, and colorectal cancer
- False decrease in fecal calprotectin concentration may be observed in patients with neutropenia or granulocytopenia.
PERFORMANCE CHARACTERISTICS
- 100% sensitivity and 97% specificity in discriminating between Active Crohn’s Disease and Irritable Bowel Syndrome.
- Interferences: Different substances that might interfere with MetaMetrics FCT were tested, and NO interferences with the following drugs were found: Azathioprin, Pantoprazol, Mesalazin, Clariothromycin, Levofloxacin, iron supplements, acetylsalicylic acid, Vitamin D, Gabapentin, Multivitamin preparation, or Ibuprofen.
TEST INFORMATION

- Turn-around Time: Cut off every Wednesday 4PM, release by Monday 12NN
- Test Kit : Each FCT Collection Set contains a Patient Collection Kit and a Laboratory Preparation Kit
â–¸ 1 Patient Collection Kit contains: 1 specimen bag, 1 stool collection cup, 2 stool collection sheets, 1 piece of gloves
â–¸ 1 Laboratory Preparation Kit contains: 1 stool sample application system
(stool sample tube with 1.5 ml sample extraction buffer), parafilm
