Modern veterinary blood banking practices and their applications in companion animal practice.

There are two main reasons for blood component therapy: the need for an increase in oxygen-carrying capacity and improved hemostasis. Additionally, blood component therapy is used to increase plasma protein concentrations. Component therapy entails separating whole blood into its cellular and plasma components and administering the appropriate blood component based on the patient's needs. General considerations such as compatibility, defined expectations of benefits, and topics including specific disease screening, preparation of blood components, preparation of blood products for administration, and typing and crossmatching in relation to blood component therapy and its application in companion animal practice are discussed.
