Preparation of Blood Components

Donated blood is separated into red cell and plasma components, each of which is transfused to treat different conditions. Some donor plasma is also sent to our Plasma Fractionation Center where it is processed biochemically to make life-saving plasma derivatives.
Transfer of Donated Blood Transfer of Donated Blood
Donated blood is transferred to the blood center in temperature-controlled containers.







Data Input Data Input
Each component's unique identification number and weight are recorded on a secure database.







Leukocyte Depletion Leukocyte Depletion
Leukocytes (white cells) are removed with a specially designed filter. This is to prevent adverse transfusion reactions caused by leukocytes.






Centrifugation Centrifugation
Centrifugation rapidly separates blood red cells from plasma: red cells are denser than plasma, so red cells move to the bottom of the blood bag and plasma moves to the top.
Separation Separation
Centrifuged blood is then divided into red cell and plasma components using an automated blood separator.







Irradiation Irradiation
Most red cell and platelet components are irradiated to prevent residual leukocytes from provoking adverse immune reactions in the recipient.
Labeling Labeling
Blood components are labeled according to their blood type and content, and packed with an additional leaflet of important information.






blood components Blood Components
After all manufacturing steps and laboratory test results are confirmed by computer, blood components can at last be considered blood products suitable for transfusion. At all stages of preparation and storage, strict environmental control (e.g. temperature and hygiene) is maintained. Fully qualified blood products are shipped to the Supply Section.

Shipping Shipping
Final inspection is performed by the Quality Department before any product can be delivered to the Supply Section.
