Fresh frozen plasma
The phrase fresh frozen plasma (FFP) refers to the liquid portion of human blood that has been frozen and preserved after a blood donation and will be used for blood transfusion. The capitalized phrase Fresh Frozen Plasma in the United States can refer to the fluid portion of one unit of human blood that has been centrifuged, separated, and frozen solid at −18 °C (0 °F) or colder within eight hours of collection. The phrase "FFP" is often used to mean any transfused plasma product. The other commonly transfused plasma, PF24, has similar indications as those for FFP with the exception of heat-sensitive proteins in the plasma such as factor V.
