Plasma from a total blood unit, isolated and frozen quickly enough after donation to maintain the activity of the different factors of coagulation at above 70% of the original.
By centrifuging a unit of total blood, the cells are separated from the plasma, which is transferred to a bag and then frozen.
The plasma contains an unmeasured amount of anticoagulant-preservative solution (CPD or CPD-Adenina).
Collapsible plastic bags.
With labels containing the following data: name of the centre, type of product, ABO group and Rh (D) factor, unit number, date of extraction, expiry date, results of analysis, types of anticoagulant, preservation and administration condition.
Fresh plasma, except in extraordinary situations, is not used for transfusions. It is an intermediate product that is treated with methylene blue or sent to industries to manufacture derivatives.
