In Australia, blood is donated by voluntary blood donors at the Australian Red Cross Blood Service. A typical whole blood donation is just over 450 mL, and it takes around ten minutes to collect. Every time a donation is made, the donor is screened for infectious disease such as hepatitis and HIV, so these aren't transferred to the patient receiving the blood.

This video looks at the various stages the donated blood goes through before it can be used in patients.
