A single bag of blood can help many patients
The Blood Service collects blood from approximately one thousand donors each day. The amount of blood collected is adapted to hospitals' blood requirements.
The various constituents of blood are known as blood components, namely red cells, platelets and plasma. Donated blood is processed by separating these components. In Component Therapy a patient only receives the blood component required. This allows several patients to benefit from a single bag of donated blood. Component Therapy is effective, and it reduces the risk of adverse effects. Donated blood as such is not transfused into patients.
Most blood products produced by the Blood Service can be delivered to the hospital immediately upon request. Blood products held in stock include leucocyte-free red cells and platelets, as well as plasma preparations. Special-purpose products are prepared according to hospitals' need.
