血常规检验的常见误差因数研究

Common error factors in blood test

为分析血常规检验的常见误差因素和解决方式,选择本院2017年5月—2017年6月接受血常规化验的100例不同科室患者为研究对象,开展血液检验,分析不同采血方式、收集样本器材、抗凝剂浓度以及不同温度对血常规结果的影响。不同温度情况下,WBC和PLT存在统计学差异,P<0.05。RBC无明显差异,P>0.05。与静脉采血相比,末梢采血的RBC、WBC以及PLT存在差异,P<0.05。稀释器以及微量加样器收集血液方式所出具的检查结果无明显统计学意义,P>0.05。但与血红蛋白吸管相比,上述两种方式所出具的结果与其存在统计学差异,P<0.05。与低浓度试剂相比,高浓度试剂处理血液样本后,红细胞比容值和平均体积有所变化,P<0.05。说明血红蛋白吸管收集血液样本、末梢采血、高浓度抗凝剂、非常温下保存血液样本,均会引起检验误差。为了避免此类误差发生,临床上应采取针对性的预防措施防止此种情况发生,同时相关工作人员应丰富自身学识,排除导致血常规样本失真的因素,按照标准流程完成相关操作,唯有这样,才能提升检验的精准性。

In order to analyze common error factors and solutions of routine blood tests,100 patients in different departments undergoing routine blood tests from May 2017 to June 2017 in our hospital were enrolled in this study.Blood tests were performed to analyze blood sampling methods,collect sample equipment,anticoagulant concentrations and the effects of different temperatures on blood routine results. There were significant differences between WBC and PLT at different temperatures( P < 0. 05). There was no significant difference,P > 0. 05. Compared with venous blood sampling,there were differences between peripheral blood sampling RBC,WBC and PLT,P < 0. 05. Dilution device and micro-sampler collected blood test results issued by no statistically significant,P > 0. 05. However,compared with the hemoglobin pipette,the above two methods issued by the results and there is a statistically significant difference,P< 0. 05. Compared with the low concentration of reagents,high concentration reagent treatment of blood samples,the value of hematocrit and the average volume changes,P < 0. 05. Hemoglobin pipette blood samples collected,peripheral blood and high concentrations of anticoagulants will cause test error. In order to avoid such errors occur,clinical precautions should be taken to prevent this from happening,while staff should enrich their own knowledge,to exclude the factors that lead to the distortion of blood samples,to complete the relevant operation according to the standard process,so as to improve the accuracy of inspection.
