摘要
目的 研究血液标本体外放置时间和温度对血液流变学指标测定的影响情况。方法 随机选取 8名受检对象 ,每人抽取 18mL静脉血 ,将每份标本根据温度分成 3组 (分别放在 4℃、2 5℃、37℃ ) ,测定 0h、2h、4h、8h、2 4h的血液流变学指标 (高切、中切、低切全血黏度 ) ,然后进行方差检验并两两比较 ,观察与 2 5℃ (室温 )放置 ,立即测定组 (0h)有无显著性差异。结果 经重复测量数据的方差分析及多重两两比较 (LSD法 )显示 :全血高、中、低切黏度在不同室温情况下及随体外放置时间的延长检测结果均有显著性变化 (P <0 .0 1)。结论 血流变指标测定受多种因素影响 ,要严格进行质量控制 ,应在 2 5℃ (室温 )、4h内得到测定。
Obejective To study relation between the hemorrheological indices and factors of blood samplers'storing time and temperature.Methods 18 mL venous blood in every 8 heathy people were divided into three groups(stored at 4℃?25℃?37℃),the hemorheological indices were tested at 0h?2h?4h?8h?24h,respectively,and statistics analysis were done.Results The results shows that hemorrheological indices significantly changed with the changes of storing time and temperature(P<0.01).Conclusion In hemorrheological indices assay,the venous blood samplers should be tested in 4 hours and at 25℃.
