1.4. BLOOD BANKS
Blood banks collect, test, and store blood. They carefully screen all donated blood for possible infectious agents, such as viruses, that could make you sick. Blood bank staff also screens each blood donation to find out whether it's type A, B, AB, or O and whether it's Rh-positive or Rh-negative. Getting a blood type that doesn't work with your own blood type will make you very sick. That's why blood banks are very careful when they test the blood.
To prepare blood for a transfusion, some blood banks remove white blood cells. This process is called white cell or leukocyte reduction. Some people are allergic to white blood cells in donated blood. Removing these cells makes allergic reactions less likely.
