摘要
目的 比较临床血常规检验中不同采血方法对检验结果的影响.方法 选取 80 例接受临床血常规检验的门诊患者,均实施末梢采血及静脉采血,检测并比较两种血样的血常规检验指标[白细胞计数(WBC)、红细胞计数(RBC)、血小板计数(PLT)、血红蛋白(HGB)、红细胞压积(HCT)]水平以及血常规检验准确率.结果 末梢血的WBC(7.44±0.19)×109/L低于静脉血的(8.59±0.23)×109/L,RBC(5.30±0.25)×1012/L、PLT(274.36±10.36)×109/L、HCT(44.07±2.37)%、HGB(143.96±8.74)g/L均显著高于静脉血的(4.67±0.12)×1012/L、(261.10±9.85)×109/L、(41.28±1.35)%、(129.96±6.37)g/L(P<0.05).静脉血临床血常规检验准确率为 95.00%,显著高于末梢血的 85.00%(P<0.05).结论 血常规检验中,采集末梢血与静脉血的检验结果存在明显差异,其中静脉血的血常规检验结果准确率较高.
Abstract
Objective To compare the influence of different blood collection methods on the results of clinical blood routine test.Methods A total of 80 outpatients receiving clinical blood routine test were selected,and their peripheral blood and venous blood were collected.Detecting and comparing the levels of blood routine indexes[white blood cell count(WBC),red blood cell count(RBC),platelet count(PLT),hemoglobin(HGB),hematocrit(HCT)],as well as the accuracy of blood routine tests in the two blood samples.Results WBC of(7.44±0.19)×109/L in the peripheral blood was lower than(8.59±0.23)×109/L in the venous blood;RBC,PLT,HCT and HGB were(5.30±0.25)×1012/L,(274.36±10.36)×109/L,(44.07±2.37)%and(143.96±8.74)g/L in the peripheral blood,which were significantly higher than(4.67±0.12)×1012/L,(261.10±9.85)×109/L,(41.28±1.35)%and(129.96±6.37)g/L in the venous blood(P<0.05).The accuracy of clinical blood routine test in the venous blood was 95.00%,which was significantly higher than 85.00%in the peripheral blood(P<0.05).Conclusion In blood routine test,there are obvious differences between peripheral blood collection and venous blood collection,with the accuracy of blood routine test being higher under the venous blood collection.
