An FDA-Cleared Gastrointestinal Test to Distinguish IBD from IBS
Calprotectin is a highly-sensitive clinical biomarker that has been shown to be extremely useful as an aid in diagnosis of inflammatory diseases in the gastrointestinal tract.
The BÜHLMANN fCAL® turbo is an in vitro diagnostic assay intended for the quantitative measurement of fecal calprotectin, a neutrophilic protein that is a marker of intestinal mucosal inflammation, in human stool. The BÜHLMANN fCAL® turbo aids in the diagnosis of inflammatory bowel disease (IBD), specifically Crohn’s disease (CD) and ulcerative colitis (UC) and aids in the differentiation of IBD from irritable bowel syndrome (IBS) in conjunction with other laboratory and clinical findings.
This FDA 510k cleared, non-invasive, sensitive and specific assay is unique in speed, quality, and flexibility. This offers accurate results and reliable information to aid clinicians in selecting patients for further diagnostic procedures.
-
Speed: fastest calprotectin test in the market, time-to-first-result within 10 minutes
-
Quality: standardized against BÜHLMANN fCAL® ELISA, uses highly precise and reproducible PETIA technology
-
Flexibility: can be applied on most open chemistry platforms streamlining your workflow using random access automation

The BÜHLMANN fCAL® turbo sets a new standard in the industry:
| A clinical study with a total of 248 adult and pediatric patients was performed to assess the ability of the BÜHLMANN fCAL® turbo to discriminate between patients with IBD and other non-inflammatory GI disorders, including IBS. A subset of this population (94 IBD vs 108 IBS) that included only samples that were run with another manufacturer’s assay were used to create the ROC curve below to provide a competitive comparison.
