Diagnostic Possibilities of Determining the Level of Faecal Calprotectin in Clinical Practice

Aim: to analyze the publications devoted to the modern possibilities of determining the level of faecal calprotectin (FCP) in the diagnosis of various diseases.Key points. In patients with already established diagnosis of inflammatory bowel diseases (IBD), dynamic monitoring of the level of FCP allows to assess the course and prognosis of the disease, as well as the effectiveness of treatment. The determining of FCP helps in the primary diagnosis of IBD (ulcerative colitis, Crohn's disease, microscopic colitis), contributing to their differentiation from functional bowel disorders, as well as in assessing the course of diverticular intestinal disease and celiac disease. The possibility of using FCP as a marker of colorectal cancer (CRC) and adenomatous polyps of the colon is also discussed.Conclusion. Determining the level of FCP plays an important role in the diagnosis and assessment of the course of a number of gastroenterological diseases (primarily IBD). The significance of FCP as a marker of CRC requires further research.
