Mayo Clinic IBD Biobank for Inflammatory Bowel Diseases

This study is collecting blood, urine, and stool samples, along with medical information, to help researchers better understand Inflammatory Bowel Disease (IBD). The goal is to improve how IBD is managed. You may be able to join if you are between 18 and 85 years old and have been diagnosed with IBD. This includes pregnant women. The study aims to enroll 1000 participants. The researchers will look at information from participants up to 50 years of age to understand the disease over time. The current recruitment status is unclear.
