Ulcerative colitis (UC) is a refractory disease characterized by symptoms such as diarrhea, bloody stools, and abdominal pain with repeated relapses and remissions.

Evaluation of UC activity is important, and endoscopic evaluations of mucosal inflammation can facilitate subsequent prognostication. On the basis of these considerations, achievement of mucosal healing is important in inflammatory bowel disease (IBD), and evaluation of IBD using endoscopy is extremely important. However, endoscopic examinations are associated with problems such as physical burden to the patient, cost, and risk of complications.

Thus, to avoid the need for frequent endoscopy, noninvasive biomarkers that accurately reflect the endoscopic activity of UC have emerged, and fecal calprotectin (FC) and the fecal immunochemical occult blood test (FIT) are being widely used in clinical practice.
