Roche Partner Channel

 for fecal Calprotectin

Since 2021 the BL fCAL turbo is offered by Roche Dx within the Partner Channel Program and allows to fill the gap for Roche Dx in the field of Gastroenterology. The program aims to combine Roche’s global diagnostic platform and market presence with partners’ specialized products, expertise, and distribution capabilities to expand business opportunities and deliver greater value to customers.

Why Calprotectin Matters

Fecal calprotectin is measured as a non-invasive biomarker of intestinal inflammation to help differentiate inflammatory bowel disease (IBD) from functional disorders, monitor disease activity, and assess response to treatment.

Challenge & Solution

The Challenge

Fecal calprotectin testing is complicated by the heterogeneous nature of stool samples, variable extraction efficiency, pre-analytical variability, and the need for reliable, reproducible quantitative results within efficient laboratory workflows.

The Solution

Standardized extraction devices, robust quantitative assays, and automated testing solutions help reduce variability, simplify sample preparation, improve reproducibility, and streamline laboratory workflows.
