Pool of citrated fresh frozen plasma from several healthy donors.

Pooled Normal Plasma consists of a pool of normal citrated human plasma from healthy donors.
The plasma pool is platelet poor with no buffers or preservatives making it most like a patient plasma.
The pooled normal plasma is then aliquoted, and rapidly frozen.
Each lot has been assayed and confirmed to contain normal levels of coagulation factors.
