New quality criteria for fresh frozen plasma

Abstract

Objective:development of new quality criteria for fresh frozen plasma.Matherials and methods: at diff erent times of storage of fresh frozen plasma harvested standardly and from the donors aft er Biolan exposure, the parameters of the kallikrein-kinin system were determined: the activity of kallikrein, the inhibitory activity of the α1 -proteinase inhibitor, α2 -macroglobulin, the total arginine-esterase activity and the level of prekallikrein.Results:during the quarantine process of fresh frozen plasma, prepared in a standard way, the processes of proteolysis activation is noticed already by 10th day from the beginning of FFP storage, and the preparation of donors for the blood donation with help of the biolan adaptogen provides better preservation of the components of the kallikrein-kinin system.Conclusions:analysis of the main components of the kallikrein-kinin system can be used as an additional criterion of the quality of fresh frozen plasma before the transfusion procedure.
