Mayo Clinic IBD Biobank

Mayo Clinic IBD Biobank

Researchers are collecting and storing blood, stool, and urine samples and medical information to better understand Inflammatory Bowel Disease (IBD) to improve disease outcome.

Subjects will be sent a letter detailing the proposed biobank and soliciting enrollment. Following the informed consent process, subjects will provide a blood sample (50 ml), urine sample (50 ml), and stool. The blood and urine samples will either be collected at the one of the Mayo Clinic outpatient laboratories or by a mail-out kit. Subjects will be asked to complete a questionnaire and 24-hour food recall questionnaire (completed online).

Inclusion Criteria:

• Patients diagnosed with inflammatory bowel disease (IBD) who are between the ages of 18 and 85 at time of study enrollment.
• The diagnosis of IBD will be based on the standard IBD criteria including biochemical and colonoscopy screening.
• Women with inflammatory bowel disease of childbearing potential and pregnant women will be offered enrollment because there is no risk to an unborn child in this investigation.
• Patients between the ages of 18 and 85 without history of IBD or colon cancer.

Exclusion Criteria:

• Patients with known liver disease.
• Patients unable to provide informed consent.
• Prisoners and institutionalized individuals.
• Patients with a history of colorectal cancer.
