Which of the following items is NOT found in cryoprecipitate?

Cryoprecipitate is a blood product rich in certain clotting factors and is derived from the thawing of frozen plasma. The primary components of cryoprecipitate include fibrinogen (Factor I), Factor VIII, and von Willebrand factor, as well as factors XIII and XIIIa.

Factor V, on the other hand, is primarily found in fresh frozen plasma and is not concentrated in cryoprecipitate. This is due to the specific processing involved in producing cryoprecipitate, where certain high molecular weight clotting factors become more concentrated, while others, like Factor V, do not.

Therefore, understanding the composition of cryoprecipitate helps clarify why Factor V is not present in it, making it the correct choice for the question regarding which item is not found in cryoprecipitate.
