Blood is a major component needed in treatment for various illnesses and injuries thanks to the many life-saving qualities present. Blood is therefore highly in demand at medical centres; up to 120,000 units of blood needed for transfusion of patients every year, an average of 400 unites of blood a day. This is why blood donors are the lifeline for such patients who need to survive on blood transfusion regularly. In order to ensure a steady supply of blood supply, it is vital for a 6-day supply of blood maintained in the national inventory. This blood is used in many medical emergencies such as accident survivors, those undergoing major surgeries (organ transplant), cancer patients with blood disorders, and many other patients who need blood.
