For preparation of cryoprecipitate the fresh frozen plasma should be
frozen within 6 hours of collection at –80oC or lower and thawed at
40C circulating water bath or in 40C cold room/Blood Bank Refrigerator.
Thawed plasma should be immediately centrifuged and separated from
the cold insoluble material under sterile conditions.
The cryoprecipitate - cold insoluble material - should be frozen within 1
hour and should be kept at -300Cor lower up to 1 year. Once thawed,
it should be used within 6 hours.
The component should contain a minimum of 0.8 IU. of factor VIII and
1.5 mg of fibrinogen per ml in at least 75% of units tested out of 1% of
