Show Answer

Correct Answer � C
Explanation
|
|
Blood Storage and Coagulation Factor Stability:
When whole blood is stored in a blood bank, certain components deteriorate over time. Among the labile coagulation factors, Factors V and VIII are the most unstable and are rapidly lost during blood storage.
Coagulation Factors – Stability in Storage:
Clinical Implications:
-
Stored blood may not be suitable for correcting coagulation deficiencies requiring Factor V or VIII.
-
Patients with bleeding disorders or massive transfusions may need fresh frozen plasma (FFP) or specific factor concentrates.
