<unk>  has similar risks to a transfusion of red blood cells and must be cross-matched to avoid hemolytic transfusion reactions. Most of the reasons for use are the same as those for RBCs, and<unk>  is not frequently used in high income countries where packed red blood cells are readily available. However, use of<unk>  is much more common in low and middle income countries. Over 40% of blood collected in low-income countries is administered as<unk> , and approximately a third of all blood collected in middle-income countries is administered as<unk> .<unk>  is sometimes "recreated" from stored red blood cells and fresh frozen plasma (FFP) for neonatal transfusions. This is done to provide a final product with a very specific hematocrit (percentage of red cells) with type O red cells and type AB plasma to minimize the chance of complications. Transfusion of<unk>  is being used in the military setting and is being studied in pre-hospital trauma care and in the setting of massive transfusion in the civilian setting.
