Whаtever sоlutiоn оr blood component is going to be trаnsfused, а donor animal will most likely be necessary. As of 2014 only four commercial blood banks exist in the United States. There is a time factor involved in receiving blood from one of these blood banks that may defeat their purpose in an emergency situation. An exceptionally busy veterinary practice may keep whole blood and blood components on hand in case of an emergency. However, because of the strict protocols that must be followed for collecting and storing blood and blood products for transfusion, many veterinary facilities have to rely on other means of obtaining blood. A typical veterinary practice relies on donor animals to provide the needed blood or blood components.
