Calprotectin Turbidimetric High Throughput Testing

Speed, Quality and Flexibility in Calprotectin Quantification

BÜHLMANN fCAL® turbo is a flexible turbidimetric assay for faecal calprotectin applicable on many major clinical chemistry platforms.


BÜHLMANN fCAL® turbo 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 many automated platforms in clinical 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 clinical chemistry analysers.

No additional pipetting and manual dilution steps are required anymore.
