Plasma frozen within 24 hours

Plasma frozen within 24 hours after phlebotomy, commonly called FP24, PF‑24, or similar names, is a frozen human blood plasma product used in transfusion medicine. It differs from fresh-frozen plasma (FFP) in that it is frozen within 24 hours of blood collection, whereas FFP is frozen within 8 hours. The phrase "FFP" is sometimes used to refer to any frozen blood plasma product intended for transfusion.

PF24 is stored, thawed, and infused with the same procedures used for FFP. Although it is technically a different product, most healthcare providers continue to refer to FFP when the actual component is PF24.
