Key Points

To explore alternative methods for producing cryoprecipitate without reliance on large refrigerated centrifuges.
Evaluated simple siphon method and two-step frozen siphon method for cryoprecipitate preparation.
Used fresh frozen plasma (FFP) stored in a blood-specific cooler for the simple siphon method.
Conducted a two-step freezing and thawing process followed by siphoning for increased recovery.
Simple siphon method achieved a fibrinogen recovery rate of approximately 49.2% and a purification rate of around 56.4%.
Two-step frozen siphon method showed a recovery rate of about 72.9% and a purification rate of 74.9%.
More than 1g of fibrinogen was recovered from 480ml of FFP using the two-step method.
