Non-fresh frozen plasma
Plasma from a total blood unit, which for several reasons does not contain the most unstable coagulation factors.
HOW IT IS OBTAINED
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.
COMPOSITION AND CHARACTERISTICS

The volume of the units is variable, according to its origin.
