Cryoprecipitate is derived from which product?

Cryoprecipitate is derived from which product?

• A. Whole blood
• B. Platelets
• C. Fresh Frozen Plasma
• D. Red blood cells

Answer: (C)

Cryoprecipitate is a plasma-derived product. It is obtained by thawing frozen plasma at cold temperatures (about 1–6°C) and collecting the small, protein-rich precipitate that forms. That sediment is rich in fibrinogen, factor VIII, factor XIII, and von Willebrand factor, all components found in plasma. Since these factors come from plasma, cryoprecipitate is prepared from Fresh Frozen Plasma, not from whole blood, platelets, or red blood cells. Whole blood can be separated into plasma and cellular components, but cryoprecipitate itself is the precipitated plasma proteins, not the cellular elements.
