摘要 目的研究分析新鲜冰冻血浆(FFP)轻度溶血对Ⅷ因子测定的影响,为今后临床血液检测及新鲜冰冻血浆质量控制提供参考。方法制备新鲜血浆,依次将0.01 g/L、0.10 g/L、0.50 g/L、1.00 g/L、2.00 g/L五种不同含量血红蛋白(Hb)标本进行冰冻,每种取样备制15份,将新鲜冰冻血浆放置于25℃常温状态解冻静置,分别在0、1、2、3、4 h不同时间节点内进行Ⅷ因子检测,对比Ⅷ因子浓度的变化情况。结果在相同血红蛋白含量血浆在冰冻不同时间内Ⅷ因子含量无明显改变(P>0.05);相同冰冻时间段内不同血红蛋白含量血浆Ⅷ因子含量无明显改变(P>0.05)。结论当新鲜冰冻血浆中血红蛋白指标<2 g/L,且25℃室温冰冻溶解环境中放置时间<4 h,则溶血不会对冰冻血浆Ⅷ因子产生明显影响。
