血常规检测的重复性和一致性研究

目的探讨血常规检测的重复性和一致性,为临床提供更准确的检验结果。方法对60例健康成人同时进行静脉血和手指末梢血的血常规检测,并放置不同时间,重复测定8次,然后对结果进行比较分析。结果静脉血和手指末梢血血常规结果差异显著,白细胞指血高于静脉血,红细胞和血小板指血低于静脉血。采血放置6h内,静脉血较手指末梢血的血常规检测,具有更好的重复性和一致性。结论在临床工作中,对血常规的检测尽量采用静脉血,并重视采血后的放置时间,才能保证结果的准确性。

Study on Repeatability and Consistency of Blood Routine Test

Objective To discuss the repeatability and the consistency of blood routine test so as to provide correct report to doctors. Methods Routine tests with venous and peripheral (ending) finger’s bloods were synchronously conducted on 60 healthy adults. The samples were laid up for various intervals and tested repeatedly (eight times).Results Significant differences in blood routine test exited between venous blood and ending finger’s blood. The white blood cell count was higher in ending finger’s blood than in venous blood, while red blood cell and platelet counts were higher in venous blood than in ending finger’s blood. The routine tests of venous blood were more repeatable and consistent than that of ending finger’s blood within six hours. Conclusion It is suggested that venous blood be utilized for clinical blood routine test and the lay-up duration be paid attention to, so that the veracity can be ensured.
