The Nicklaus Children's Hospital biobank and tissue repository is an essential resource for personalized medicine research efforts, enabling the study of both health and disease over time. The Biobank collects samples and health information from volunteers, regardless of health history. Once a participant becomes part of the Biobank, he or she contributes to ongoing health research. We partner with Sanford Health, a national leader on specimen storage, management and integration with participant health information.
