摘要
目的 了解血液分析仪测定静脉血和末梢血血常规结果的差异。方法 同时采集 116例住院患者的静脉血和末梢血 ,用EDTA -K2 抗凝 ,用CELL DYN170 0血液分析仪测定血常规结果 ,所得两组数据经统计学和相差分析 ,比较静脉血和末梢血的差异。另外选择 12例患者抽静脉血 46份 ,9例患者采末梢血 33份 ,每例患者在两周内均采 3～ 5份 ,对得到的静脉血和末梢血 8种参数结果的变异系数 (CV值 )进行统计学分析 ,比较其结果差异。结果 血液分析仪测定静脉血和末梢血血常规结果显示 ,两组WBC、RBC、HGB、MCH、MCHC、PLT的均有明显差异 ;末梢血各参数的CV值大于静脉血。结论 血液分析仪测定血常规时 ,最好用EDTA -K2 抗凝的静脉血。
Objective To learn the difference of blood routine between vein capillary blood examined by automatic hematologic analyser. Methods For same blood samples of 116 hospitalized patients were adopted, anticoagulated by EDTA-K 2 and examined by CELL DYN 1700 automatic hematologic analyser for blood routine.These two groups' data (measured) were compared through statistics and residual quantity analysis. And then 46 samples of vein blood were adopted from 12 patients,33 samples of capillary blood samples form 9 cases and each patient was equally adopted 3～5 times in two weeks. Average coefficient of variation (CV) of vein and capillary blood was compared. Results WBC,RBC,HGB,MCH,MCHC,PLT measured by the above two methods had evident difference. CV of the capillary blood was more than that of vein blood. Conclusion It was better to use vein blood anticoagulated by EDTA-K 2 when blood routine was examined by automatic hematologic analyser.
