Question: 1 / 400

How long is cryoprecipitate viable once it has been thawed?

2 hours

4 hours

Cryoprecipitate is a blood product primarily composed of fibrinogen, factor VIII, and von Willebrand factor, which are crucial for blood clotting. Once thawed, cryoprecipitate should be used within a specific time frame to maintain its viability and effectiveness.

The correct answer indicates that thawed cryoprecipitate is viable for four hours. This time frame is crucial because, after this period, the components, especially fibrinogen, can begin to degrade or may not perform effectively in hemostatic processes.

Additionally, regulatory guidelines often recommend that thawed cryoprecipitate be used promptly to ensure that patients receive the maximum potential benefit from its clotting factors. Thus, adhering to this four-hour window is essential for optimal patient care and safety in blood banking practices.
