Clinical Info
This test measures mucosal healing status in Crohn’s disease patients. The test applies an algorithm to the concentrations of 13 biomarkers in order to produce a quantitative Mucosal Healing Index Score ranging from 0-100. The Mucosal Healing Index Score is intended to aid in the assessment of active disease in Crohn’s disease patients in conjunction with clinical evaluation performed by a healthcare professional. It is not validated or intended for use in diagnosing Crohn's disease.
