Fresh frozen plasma (FFP) is a crucial substitute therapy in management of bleeding; producing plasma from whole blood stored within 24 h offers operational flexibility and leukocyte filtration significantly reduce transfusion reactions, it is necessary to consider the impact of these plasma preparations on clotting factors activity. Total of 75 plasma samples collected from 25 blood donors distributed as 3 groups; FFP (Group A), leukocyte filtrated FFP (Group B) and plasma frozen within 24 h i.e. PF24 (Group C), for all samples prothrombin time (PT), INR, (APTT), Factors V, VII, VIII, IX levels and Fibrinogen were done, also comparing coagulation factors levels in FFP in different blood groups. There were significant difference between three groups in (PT), INR and (APTT): (P = 0.00). Concerning Factor VII: significant difference (P = 0.03) between the three groups, FFP had a significantly higher level of FVII compared to filtrated FFP (98.92 vs. 82.52%; P = 0.02), while no significant difference between FFP and PF24 was detected (P = 0.76). Factor VIII: had significant difference (P = 0.00) between the three groups, FFP and Filtrated FFP had no significant difference regarding level of FVIII (P = 0.72), but FFP had significantly higher level of FVIII compared to PF24 (P \ 0.05). Concerning Fibrinogen level: no significant difference between FFP and filtrated FFP (P = 0.99), while FFP had a higher level versus PF24 (P \ 0.05). On the Contrary, no significant difference between three groups in Factor V: (P = 0.22) and Factor IX: (P = 0.12). ABO blood group effect on studied parameters in FFP: FVIII was statistically higher in Non-O blood group (P = 0.03), other factors had no statistical differences (P [ 0.05). The leukocyte filtration of FFP did not affect the majority of coagulation factors activities, although FVII level was reduced, it stills enough for surgical hemostasis. The PF24 resulted in reduced FVIII and fibrinogen levels but no significant changes in FV, FVII or FIX, thus, can be used for FFP indications except that specifically requiring replacement of FVIII and/or fibrinogen as Hemophilia or DIC. No significant difference in coagulation factors of FFP between O and non-O blood groups except FVIII that was reduced in O blood group.
