Cryoprecipitate is most commonly used to replace which plasma protein?

• A. Fibrinogen
• B. Prothrombin
• C. Factor VII
• D. Factor XI

Answer: (A)

Cryoprecipitate primarily replenishes fibrinogen, a central clotting protein essential for forming the fibrin mesh that stabilizes clots. When fibrinogen levels drop during significant bleeding or certain coagulopathies, giving cryoprecipitate increases fibrinogen quickly and helps restore proper clot formation. Although cryoprecipitate contains other factors (like factor VIII, factor XIII, and von Willebrand factor), its main role is to supply fibrinogen. Prothrombin (factor II), factor VII, and factor XI are not provided in reliable amounts by cryoprecipitate and are instead addressed with other products such as fresh frozen plasma or specific factor concentrates.
