A blood bank is a crucial healthcare facility that stores, tests, and distributes blood and its components for transfusions. These establishments play a vital role in saving lives during emergencies, surgeries, and treatments for various medical conditions like cancer and anemia. Donated blood undergoes rigorous screening to ensure safety and compatibility. Additionally, blood banks often conduct community blood drives to replenish their supplies. Through their efforts, blood banks contribute significantly to healthcare systems worldwide, providing a lifeline for patients in need.
