We are excited to announce that Gentian will be exhibiting at CORA 2025, the Congress on Controversies in Rheumatology & Autoimmunity, taking place on March 6–8, 2025, in Venice.
Join us at our booth to learn more about calprotectin’s potential as a biomarker in rheumatic diseases and how Gentian’s GCAL® calprotectin assay is advancing diagnostics in this field.
Discover the power of circulating calprotectin
Calprotectin is gaining attention as a valuable inflammatory biomarker in rheumatology offering insights into disease activity:
- Calprotectin levels correlate with disease activity in inflammatory rheumatic diseases (IRDs) 1-7
- Valuable tool to monitoring disease activity, treatment response and relapse 8-10
- Risk marker for flares to guide treatment withdrawal 11-15
- Differential diagnosis of Still’s disease in children with fever of unknown origin 16
Calprotectin testing is now recommended in EULAR, ACR, and PReS guidelines.
Explore GCAL®
The Gentian GCAL® Calprotectin Immunoassay is a fast, reliable, and fully automated solution for measuring circulating calprotectin in plasma and serum. Designed for seamless integration, GCAL® offers easy setup and broad compatibility with major clinical chemistry analysers, making it an efficient and scalable choice for both small and large laboratories.
Our team is ready to assist with your questions and validation setup for GCAL®, ensuring seamless integration into your laboratory or the laboratory you use.

Meet our team and learn how to integrate circulating calprotectin into your clinical practice and laboratory
If you’re attending CORA 2025, don’t miss this opportunity to discover how Gentian’s GCAL® assay can help improve patient management through sensitive and reliable inflammation detection that can enhance diagnostic output in rheumatology.
