Abstract:
【Objective】 To investigate the factors affecting the quality of cryoprecipitated antihemophilic factor. 【Methods】 The quality test results of cryoprecipitated antihemophilic factor in Xuzhou Central Blood Station from 2017 to 2020 were selected and compared. The fresh frozen plasma (FFP) was stratifying by storage time following whole blood collection: less than 2h, 2~4 h, 4~6 h, and 6~8 h; by gender: males and females; by blood group: A, B, O, and AB groups; by age: 18~30, 30~45, and 45~60 ages; by preparation method: centrifugation and siphonage. The contents of fibrinogen (FIB) and factor Ⅷ in cryoprecipitated antihemophilic factor in each group were compared. 【Results】 The content of FIB and factor Ⅷ in females were higher than those in males(P<0.05). The content of factor Ⅷ differed statically by blood groups (P<0.05), which was lower in group O than others [graup A(180.5±75.2)IU, graup B(155.1±59.4)IU, graup O(109.3±46.4)IU, graup AB(168.5±65.1)IU]. The content of factor Ⅷ increased with age statistically (P<0.05). The content of FIB prepared by centrifugation [(373.3±126.1)mg] was superior to siphonage [(309.4±85.6)mg] (P<0.05), while the content of factor Ⅷ prepared by siphonage [(172.4±71.3)IU] was superior to centrifugation [(124.0±49.1)mg] (P<0.05). 【Conclusion】 Gender and preparation method are the influencing factors of FIB. Gender, age, blood group and preparation method are the influencing factors of the content of factor Ⅷ. The FFP prepared by whole blood preserved with the ACD (citrate, sodium citrate and glucose) solution at any time within 8h after the collection has no impact on the quality of cryoprecipitated antihemophilic factor.
