Microbiome Test for the Detection of Colorectal Polyps and Cancer
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

The purpose if this study is to measure the sensitivity, specificity and accuracy of the Metabiomics Colon Polyp and Colorectal Cancer Assay for the non-invasive detection of colon polyps or colorectal cancer.
Condition or disease
Colorectal NeoplasmsColorectal Cancer
The purpose of this study is to conduct clinical research to investigate the association of the gut microbiome with colonic neoplasia. In this study patients will supply samples of their gut microbiome prior to scheduled colonoscopy; the relative abundance of microbes from those samples will be used to predict the presence or absence of colon polyps or colorectal cancer. Microbiome based predictions from blinded samples will be compared with colonoscopy and pathology results to quantify the sensitivity, specificity and accuracy (reported as %) of the Metabiomics Colon Polyp and Colorectal Cancer Assay for colon polyps. The limited sample size is anticipated to be insufficient to quantify sensitivity to colorectal cancer.
Performance of Metabiomics Colon Polyp and Colorectal Cancer Assay [ Time Frame: 1 year ]
Microbiome based predictions from at least 100 blinded samples will be compared with colonoscopy and pathology results to quantify the sensitivity, specificity and accuracy (reported as %) of the Metabiomics Colon Polyp and Colorectal Cancer Assay for colon polyps. The limited sample size is anticipated to be insufficient to quantify sensitivity to colorectal cancer.
Biospecimen Retention: Samples With DNA
gut microbiome samples from stool, rectal and colonic mucosa
