Blood and blood components are biological products, and in the form of cellular products are living human tissue intended for use in the treatment of patients.
Transfusion can effectively and efficiently provide or replace missing or malfunctioning elements of the blood or immune systems.
Some types of anaemia, thrombocytopenia and platelet function disorders, bleeding disorders, and massive transfusion are common clinical indications for blood components.
Clinicians are encouraged to adopt the principles of patient blood management (PBM). The National Blood Authority Patient Blood Management Guidelines and other evidenced-based clinical guidelines provide specific decision support regarding appropriate transfusion practices and the use of blood components.
