Inflammatory bowel diseases are chronic diseases that result from an inflammation of the intestinal wall. They are suspected in any patient presenting with intestinal symptoms. Until recently, diagnosis was mainly based both on clinical and endoscopic arguments. The use of an easy, fast, reliable, non-invasive and inexpensive test must not only assist in the diagnosis but also contribute to their evolutionary and therapeutic monitoring. To date, fecal calprotectin is the most documented in this perspective. This marker allows to discriminate between functional and organic bowel processes with good sensitivity and good specificity. The determination of the fecal calprotectin level in stools contributes to the evaluation of the degree of disease activity and monitoring of therapeutic response.
