Role of Fecal Calprotectin as a Noninvasive Indicator for Ulcerative Colitis Disease Activity.

Background: It is essential in clinical management to determine the disease activity in ulcerative colitis (UC) patients. At present, the most accurate way of evaluating the UC severity is endoscopy with biopsy. Fecal calprotectin (FCP) is a non-invasive biomarker that is frequently used for monitoring of intestinal inflammation.
