The management of inflammatory bowel disease (IBD), which is characterized by immunodeficiency, has attracted increasing attention, highlighting the necessity for more precise and streamlined diagnostic approaches in clinics. Calprotectin, an immune cell-derived protein with inherent anti-inflammatory and antimicrobial properties, plays a pivotal role in immune regulation and intestinal homeostasis. Its expression levels are intricately linked to IBD activity, enabling differentiation between inflammatory and non-inflammatory states while predicting recurrence risks. As a non-invasive biomarker, fecal calprotectin (FC) and serum calprotectin (SC) analysis offers high reproducibility and clinical utility, facilitating both IBD diagnosis and real-time disease monitoring. Beyond its diagnostic specificity in distinguishing IBD from other gastrointestinal disorders, calprotectin also emerges as a promising therapeutic target, due to its dual role in modulating inflammatory pathways and interacting with the gut microbiota. With collaborative advancements in standardized detection protocols and innovative research methodologies, it is anticipated that calprotectin-based strategies will be integrated into mainstream clinical practice for IBD.
