FFP stands for Fresh Frozen Plasma. It is the liquid portion of whole blood that has been separated and frozen shortly after blood donation, typically within 8 hours. It contains all the coagulation factors, proteins, and other substances necessary for blood clotting and is used to treat patients with clotting factor deficiencies or bleeding disorders. FFP is thawed before transfusion and helps restore clotting proteins to stop or prevent bleeding in conditions like warfarin overdose, liver disease, and thrombotic thrombocytopenic purpura (TTP) among others. It provides volume resuscitation and replaces deficient plasma proteins but can have side effects like allergic reactions or volume overload.

Additionally, in another context, FFP can refer to Financial Fair Play, a set of regulations in European football (soccer) designed to prevent clubs from spending more than they earn to ensure financial sustainability, but the primary and most common meaning medically is Fresh Frozen Plasma.
