Cryoprecipitated AHF is indicated for?

Cryoprecipitated AHF (Antihemophilic Factor) is specifically indicated for the management of fibrinogen deficiencies. It is a blood product derived from fresh frozen plasma and is rich in fibrinogen, factor VIII, and fibronectin, making it essential in treating patients with low fibrinogen levels, which are often associated with conditions like disseminated intravascular coagulation (DIC) or congenital fibrinogen deficiency.

The other options do not align with the primary role of cryoprecipitate. While storage at 4°C is relevant for blood products, it is not a specific indication for cryoprecipitated AHF's use; rather, it's a general requirement for maintaining its efficacy prior to administration. The claim regarding the transmission of hepatitis B virus does not reflect the intended therapeutic purpose of cryoprecipitate, as it is produced under guidelines designed to minimize such risks. Finally, cryoprecipitate is not used for the treatment of hemophilia B; instead, it is utilized for hemophilia A where factor VIII is deficient. Thus, the focus on fibrinogen deficiencies accurately highlights the critical application of cryoprecipitated AHF in clinical practice.
