Core Tip
Core tip: Scientists are always searching for new disease biomarkers. An acceptable biomarker could help us in early diagnosis and classification of the diseases as well as the prediction of disease outcome. The diagnosis of gastrointestinal (GI) diseases is usually based on techniques such as upper or lower GI endoscopy, while highly sensitive and specific non-invasive diagnostic or screening tools are usually lacking. In this review, we have discussed the potentials of urinary metabolomics study as a future tool for the screening, diagnosis, classification and surveillance of GI diseases including inflammatory bowel disease and cancer.
