About this study

The purpose of this study is to collect blood and stool samples to validate and improve the performance of stool and blood DNA markers for inflammatory bowel disease and colorectal neoplasia critical to the long-term goal of improving effectiveness of neoplasia detection in patients using non-invasive biomarkers to assist colonoscopy and radiographic screening.
