A biobank is a repository that stores biological samples, such as blood, tissue, and DNA, along with relevant health information from individuals. These samples are typically collected from patients with specific medical conditions, healthy individuals, or populations for use in research studies. Biobanks play a crucial role in advancing medical research by providing researchers with access to large, well-characterized sample collections that can be used to study the underlying causes of diseases, identify biomarkers, and develop new treatments. Biobanks also play a key role in personalized medicine, as they can help researchers understand how genetic and environmental factors influence individual health outcomes.
