血常规检验前采血标本质量控制的问题及应对措施

Problems and countermeasures of quality control of blood sampling specimen before routine blood test

目的:分析血常规检验前采血标本质量控制的问题及应对措施。方法:收治接受血常规检验患者72例,分析检验结果,观察不同采血部位和不同检测时间对检测结果的影响。结果:静脉血的白细胞、红细胞、血红蛋白水平明显高于末梢血,静脉血的血小板计数低于末梢血,数据对比后差异有统计学意义(P<0.05)。立即检测的数值明显高于<6 h和≥6 h的。结论:提升血常规检验结果准确率是重点和关键,能减少标本误差。

Objective:To analyze the problems and the countermeasures of quality control of blood sampling specimen before blood routine examination.Methods:72patients underwent routine blood test were selected,and the results were analyzed.The effects of different blood sampling sites and different detection time on the final detection results were observed.Results:The WBC,RBC and Hb in venous blood were significantly higher than those in peripheral blood,and the platelet coefficient in venous blood was lower than that in peripheral blood.After the data contrast,the difference was statistically significant(P<0.05).Numerical detected immediately was significantly higher than that of less than6h and above6h.Conclusion:Improving the accuracy of routine blood test is the key point and the key to reduce the sample error.
