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 better understanding of conditions like cancer, diabetes, and heart disease. By analyzing samples from diverse populations, biobanks help ensure that medical advancements benefit everyone.
