真空静脉采血顺序对血细胞分析结果的影响

Influence of Vacuum venous blood order on the results of blood cell analysis

目的探讨一针多管真空采血顺序所致血细胞分析结果差异,并观察含添加剂的真空管是否会对真空血常规管造成试剂交叉污染,导致结果有差异。方法采用自身对照法,对196例门、急诊患者一次进针、多管采血、不同顺序前后2次使用真空血常规管,测定血细胞分析结果。结果采集2次标本的血细胞分析指标,白细胞、红细胞、血红蛋白、血小板,采用配对t检验,2次结果差异无统计学意义(P>0.05)。结论在一针多管真空采血中,真空血常规管不受采血顺序的影响,血细胞分析也不受含其他添加剂真空试管的交叉污染影响。

Objective To investigate the difference of blood routine analysis in a multi-tube vacuum blood collection needle mod- el and judge whether the vacuum tubes containing additives have any effect on the vacuum caused by routine blood test tube reagent cross-contamination. Methods Self-control method were adopted to detect 196 outpatient and emergency patients in a different order of routine blood test before and after the vacuum tube was used twice to measure blood cell analysis. Results There is no significant difference between the two specimens of blood cell analysis indicators, white blood cell, red blood cell, hemoglobin and platelets （P〉0.05）. Conclusion In a multi-tube vacuum blood collection needle,the vacuum tube from routine blood test the impact of the order of blood,blood cell analysis with other additives are not subject to the pollution impact of the vacuum tube.
