The present invention provides methods for diagnosing inflammatory bowel disease (IBD) or for differentiating between Crohn's disease (CD), ulcerative colitis (UC), and indeterminate colitis (IC) in an individual by using a combination of learning statistical classifiers based upon the presence or level of one or more IBD markers in a sample from the individual. The present invention also provides methods for diagnosing the presence or severity of IBD and for stratifying IBD in an individual by determining the level of one or more IBD markers in a sample from the individual and calculating an index value using an algorithm based upon the level of the IBD markers. Methods for monitoring the efficacy of IBD therapy, monitoring the progression or regression of IBD, and optimizing therapy in an individual having IBD are also provided.
