A biobank is a facility that collects, stores, and manages biological samples, such as blood, tissue, and DNA, for research purposes. These samples are often linked to health information, allowing scientists to study diseases, genetics, and the effects of treatments. Biobanks play a crucial role in advancing medical research and improving public health. Researchers use biobanks to find patterns and correlations in health data, which can lead to new discoveries and therapies. By analyzing samples from diverse populations, biobanks like the UK Biobank help ensure that findings are applicable to various groups, enhancing the effectiveness of medical interventions.
