Which cryoprecipitate unit has the highest AHF activity?

• A. Unit 2
• B. Unit 3
• C. Unit 4
• D. Unit 1

Answer: (D)

AHF activity reflects the amount of Factor VIII in a cryoprecipitate unit. Cryoprecipitate concentrates several clotting factors, especially Factor VIII (AHF), along with fibrinogen, Factor XIII, and von Willebrand factor. When aiming to raise Factor VIII levels, you want the unit with the highest Factor VIII content because that delivers the most AHF activity per transfused unit. Therefore, the best choice is the unit with the greatest AHF activity, which in this case is Unit 1. The other units have lower AHF activity and would contribute less Factor VIII.
