Details and patient eligibility

About

The ALPCO Calprotectin ELISA is an in vitro diagnostic test intended to quantitatively measure concentrations of fecal calprotectin in human stool samples. Calprotectin is a protein biomarker of mucosal inflammation. Measurement of calprotectin can aid in the diagnosis of Inflammatory Bowel Diseases (IBD), specifically Crohn's Disease (CD) and Ulcerative Colitis (UC), as well as aid in the differentiation of IBD from Irritable Bowel Syndrome (IBS) when used in conjunction with other diagnostic testing and the total clinical picture. This study will estimate the predictive values of a negative (NPV) and positive (PPV) test by utilizing the assay outcomes of the ALPCO Calprotectin ELISA.
