Evidence-based biomarker
Recommended by ECCO, NICE, and AGA guidelines, calprotectin is an early detector of inflammation, differentiates IBD from IBS, and provides objective diagnostic and prognostic information. By enabling sub‑clinical detection of flare, early intervention, and close‑to‑real‑time mucosal healing assessment, calprotectin testing can support both immediate clinical decisions and long‑term disease management.

Every year on May 19, World IBD Day brings attention to the reality of living with Crohn’s disease and ulcerative colitis. More than ten million people worldwide manage these conditions every day, navigating flares, treatment decisions, and the uncertainty of a disease with no cure. Awareness matters. But for clinicians treating IBD, awareness is not…

Fecal calprotectin (fCal) is an essential biomarker for monitoring inflammatory bowel disease (IBD), helping ensure patients receive the right treatment at the right time. As patient-centered care grows, remote monitoring tools like the CalproSmart self-test offer an efficient alternative to traditional lab-based methods. But do these two different analyses give the same fCal results? This…

In this case study, we get insights from MUDr. Karin Černá, from the ISCARE Clinic in the Czech Republic. The clinic has a distance care service aiming for improved remote care of Inflammatory Bowel Diseases (IBD). As of the beginning of 2022 in the Czech Republic, remote care for patients diagnosed with IBD is covered by public…
