Preserved plasma ready for transfusion to patients according to their particular needs. Plasma is a protein-salt solution that is the liquid component of blood in which blood cells are suspended; plasma is taken from donors\' blood that is not intended for pathology tests. After separation from the blood cells, plasma is quickly frozen after donation to preserve clotting factors and can be stored frozen up to one year . Preserved plasma is usually stored in blood banks and mainly used after trauma, burns, and severe liver and/or bleeding disorders.
