Q: Cryoprecipitate as name applied can be kept frozen for clinical use for how long?

Answer: About one year.

Fresh-Frozen -Plasma obtained from one unit of blood is thawed at 4°C for about 24 hours, which makes precipitates of cold-insoluble proteins, which are very rich in blood coagulation factors. It is re-frozen at -18°C. Total amount of cryoprecipitate obtained from one unit of blood is about 10-15 mL. This product can be kept frozen at -18°C for about one year to use for clinical transfusions.
