BÜHLMANN fCAL® turbo is for Research Use Only. Not to be used in diagnostic procedures.

The technology of immunoturbidimetry implements a further milestone in fecal calprotectin quantification. It allows very rapid and flexible random access use, as well as being the ideal solution for high throughput applications in the routine laboratory. The assay can be applied on all automated platforms in chemistry and allows short turnaround time from stool sample to reportable result. The combination of the test with the BÜHLMANN CALEX® Cap extraction device strongly simplifies the cumbersome procedure for stool pre-analytics and is adapted to the use on chemistry analyzers. No additional pipetting and manual dilution steps are required anymore.

  • Speed The assay is the fastest calprotectin test in the market. Results are given within 10 minutes. The broad measurable range of direct testing from 20 to 2000 µg/g calprotectin reduces the amount of retesting down to <5%.
  • Quality The assay is standardized against the BÜHLMANN fCAL® ELISA. Particle-enhanced turbidimetric immunoassay (PETIA) further increases the precision and reproducibility of calprotectin quantification.
  • Flexibility Immunoturbidimetric assays can be applied on any open chemistry platform. This allows random access workflow which can be directly integrated into the existing laboratory infrastructure.
