Non-fresh frozen plasma

Plasma from a total blood unit, which for several reasons does not contain the most unstable coagulation factors.

Frozen plasma can come from different origins:

Plasma obtained in the same way as fresh plasma, but which has been frozen after more than 24 hours and, consequently, the level of the most unstable factors (factor V and factor VIII) are not optimum.
Plasma that has been thawed and frozen again.
Plasma from a surplus of a cryoprecipitation.

The composition of this plasma is not controlled, as it is not used for transfusions.
The volume of the units is variable, according to its origin.
