Description

含有酯类化合物的血液流变质控组合物 技术领域
本发明涉及医学诊断领域中血液流变指标检测技术, 更具体地说, 涉及一 种含有酯类化合物的新型血液流变质控组合物。 背景技术
宏观临床血液流变学检测的最基本指标应包括全血粘度、血浆粘度、红细 胞压积和血浆纤维 蛋白原测定。 血液是复杂的非牛顿流体, 它的表观粘度随 剪切率和剪切时间而变异。血流变检测的质控相当复杂, 又由于缺乏标准参考 物质, 使不同医院、 不同仪器检测的血流变临床数据缺乏可比性, 影响了血液 流变检测的临床应用。 因此,研制一种合适的血流变质控物是本领域技术人员 关注的问题。 国内外报道了一些对血液粘度质控物的相关研究。 张宁等(血液粘度室内 质控物的研究与应用, 中华医学检验杂志, 1997, 20 (1): 41 ~42)研究用聚 合物乙二醇 -6000 溶液作为全血粘度检测质控物; Brookshier KA等
