临床血常规检验中常见的误差问题分析

Analysis of Common Errors in Clinical Blood Routine Examination

目的对临床血常规检验中常见的误差问题进行分析,将产生问题的原因进行思考,同时采取相应的解决对策,以最大程度将血常规检验的准确性提高,最大程度减少血常规检验结果误差时间的发生。方法选取2018年1月至2019年1月来我院接受血常规检验的患者120例血常规标本作为本次研究资料,采用全自动血细胞分析仪进行检测,对末梢采血、静脉采血、放置的温度环境及存放时间进行对比,其中2018年1月至2018年6月来接受血常规检验的患者(60例)采用了常规血常规检验方式(采血4 h后进行检测,室温保存,指尖采血),2018年7月至2019年1月来接受血常规检验的患者(60例)在采用常规血常规检验方式的基础上,对导致出现误差的原因进行分析,并进行处理(采血后2 h进行检测,冰箱保存,静脉抽血)。结果在临床血常规检验的过程中,血液放置时间过长、温度保存不当、抽血部位不同,均会对血常规检验结果造成误差,通过对血液放置时间、放置温度和采血方式进行改善,可明显提升血常规结果,差异有统计学意义(P <0.05)。结论在血常规标本检验过程中,温度环境、存放时间、检验方法、采血部位都会造成血常规检验结果准确性出现误差,一旦出现误差,将严重影响患者的治疗效果及预后情况,因此,在临床检验的过程中,应加强整个检验过程中的质量控制,且静脉采血方式相对来说准确性更高,且与患者的实际指标情况更为符合,因此,静脉采血可作为临床中接受血常规检验患者的首选采血方式。

Objective To analyze the common error problems in clinical blood routine examination, to think about the causes of the problems, and to take corresponding countermeasures, in order to maximize the accuracy of blood routine examination, to minimize the error time of blood routine examination results. Methods Selection in January 2018 to January 2019 to our hospital in patients undergoing routine blood test specimens of 120 cases of blood routine as the research data, using automatic blood cell analyzer for testing, of peripheral blood and venous blood collection and placement, comparing the environment temperature and storage time of which come from January 2018 to June 2018 in patients undergoing routine blood test(60 cases) adopted the conventional way of routine blood test, blood test after 4 h, room temperature preservation, finger tip blood), From July 2018 to January 2019, 60 patients(60 cases) received routine blood tests, and on the basis of routine blood tests, the causes of errors were analyzed and treated(2 h after blood collection for testing, refrigerator storage, venous blood sampling). Results In the process of clinical routine blood test, blood storage time is too long, improper temperature preservation, blood is different, all can cause the error, the routine blood test results through the blood to place, placing temperature, time and ways to improve blood can obviously improve the blood routine as a result, the difference was statistically significant(P<0.05). Conclusion In the process of specimens of routine blood test, environment temperature, storage time, inspection method, blood will appear routine blood test result accuracy error, once appear error, will affect the treatment effect and prognosis of patients with severe situation, therefore, in the process of clinical inspection, should strengthen the inspection process quality control, and venous sampling method is relatively higher accuracy, and with the patient is more conform to the actual index, therefore, venous blood can be used as a routine blood test of choice for patients with blood in clinical.
