  • After your unit of blood is collected - along with several small vials used for testing - your blood donation is labelled and transported to laboratory.
  • Whole blood donations are separated into three essential components—red cells, platelets, and plasma.
  • Your blood is typed, which includes identifying the ABO type and a positive or negative Rh factor, and each vial of blood is tested for safety, including tests for:
    • HBV (Hepatitis B Virus)
    • HCV (Hepatitis C Virus)
    • HIV (the virus that causes AIDS)
    • Syphilis
    • Unexpected red cell antibodies that the donor may have formed in response to an earlier exposure to blood, through either transfusion or pregnancy.

  • No blood is released for transfusion without passing the required tests. Although it is rare to find donated blood that may transmit infection, those units of blood that are reactive for viral markers are not released for transfusion. A combination of pre-donation screening and rigorous testing ensures the safety of blood. In addition, as a safety precaution, a list of ineligible blood donors is maintained and donors are checked against this list before allowing them to give blood.
  • After your blood has been divided, passed all tests, and been properly typed and labelled, it is stored in specialized designatedrefrigerators and freezers. It is now ready for distribution to hospitals and to the patients whose lives will be saved or sustained by this generous gift.
  • The blood components are carefully packed in special temperature-controlled containers and then transported via delivery trucks or authorized couriers to the hospitals.
  • The final step in your donated blood’s journey is when the right type of donation you have made reaches the right patient—typically within 10 days. Consider the need and the lives you can save by matching your donation to the blood component patients need most.
