Gastrointestinal bleeding is a common symptom of various gastrointestinal diseases, including colorectal carcinoma, colon polyps, ulcerative colitis and Crohn’s disease, and early detection of occult bleeding is critical for timely disease diagnosis and intervention. Colorectal carcinoma, in particular, is a prevalent malignant tumor, and occult gastrointestinal bleeding is often its early clinical sign, making reliable bleeding detection biomarkers essential for screening.
