Every hour of the day, 15 units of blood are used in Singapore. More than 100,000 units of blood are needed to meet the transfusion needs of patients every year, equivalent to more than 350 units of blood a day.

With an ageing population, more advanced life-saving medical procedures, and new hospitals being established, more blood will be needed every year.

Therefore, to ensure a steady supply of blood for public use in peacetime and during emergencies, it is vital that a 6-day supply of blood is maintained in our national inventory.
