A biobank, or biorepository, is an important resource for medical research. Essentially, it is a collection of both biological samples (e.g., blood, urine, saliva, or leftover tissue) and health information pulled from medical records, such as past surgeries, medications, and specific medical conditions. These biological samples and data come from biobank donors: individuals who have agreed to participate in the biobank by providing them with a biological sample and access to their medical records. The fundamental purpose of a biobank is to provide researchers with de-identified biological samples and data. These samples are often stored in specialized freezers for long-term use, meaning materials requested by researchers could have been collected recently or many years prior.
