Fecal calprotectin (fCAL) is the most important marker for in vitro diagnostic detection of gut inflammation. Immunological quantitation is well established and is used in the diagnostic process of inflammatory bowel diseases (IBD) and in the lifelong monitoring of these chronic conditions. fCAL testing today requires a significant level of lab resources including stool sample handling, extraction and the use of traditional immunological testing methods. The BÜHLMANN fCAL turbo assay is a big step towards full automation. It reduces the time to result as well as the total hands-on time significantly. It offers the possibility of random access and is independent of the clinical chemistry platform. Validated applications are available for the most common analysers. The combination with the proprietary extraction device CALEX Cap for pre-analytical sample preparation simplifies and accelerates stool diagnosis significantly. The BÜHLMANN fCAL turbo utilizes the well-established standardization of the BÜHLMANN fCAL ELISA to provide reliability and continuity of measurements.
