检验前质量控制在生化检测中的重要性分析

目的分析生化检测中检验前采取质量控制的重要性,以便为临床生化检验提供借鉴。方法将自愿参与研究的40例行生化检测的对象均分为对照组与实验组,各自20例。两组患者先按照常规临床生化检测标准中有关于检测前质量控制标准行血常规检测,1周后,实验组对象依旧根据生化检测标准执行,而对照组则在检验前按照指定检测标准执行,即不进行检测前质量控制,主要有检测前禁食,但晚上饮食无食品限制,同时晨检测前吃早餐等。本次研究中将生化检测中血液红细胞计数作为观察指标,比较分析两组对象血液红细胞计数情况。结果实验组初次生化检测与1周后再次生化检测所得血液红细胞计数均值依次为（3.45±0.42）×10^12/L、（3.57±0.54）×10^12/L,对照组则分别为（3.56±0.48）×10^12/L、（4.83±0.69）×10^12/L,两组对象初次生化检测所得血液红细胞计数比较差异无统计学意义（P〉0.05）,但1周后再次检测所得血液红细胞计数比较差异有统计学意义（P〈0.05）,同时组内比较来看,对照组初次与再次检测所得结果比较差异有统计学意义（P〈0.05）,而实验组初次与再次检测所得结果则无统计学意义（P〉0.05）。结论生化检测中检验前加强质量控制可以明显提高检测质量与效率,有着积极的意义,值得借鉴。

An analysis of the significance of pre-test quality control in biochemical tests

Objective To analyze the significance of pre-test quality control in biochemical tests,so as to provide supports for clinical biochemical tests. Methods 40 patients who participated in the study voluntarily and received biochemical tests were allocated to a control group and an experimental group, with 20 in each.Routine blood tests were carried out in the two groups according to the standard of pre-test quality control under the regular clinical standard of biochemical tests.After one week,patients in the experimental group continued to follow the standard of biochemical tests,while the control group followed a specified standard before tests without the pre-test quality control,which entailed pre-test fasting, but the diet is not restricted in the evening, and breakfast should be eaten before morning tests.Red blood cell count in the biochemical tests was taken as an observation index in the study,and the count was compared and analyzed between the two groups. Results The average red blood cell counts taken in the first biochemical test and in the second biochemical test one week later in the experimental group were（3.45±0.42）×10^12/L and（3.57±0.54）×10^12/L respectively,and in the control group were（3.56±0.48）×10^12/L and（4.83±0.69） ×10^12/L respectively.The difference of red blood cell counts taken in the first biochemical test in the two groups were not statistically significant（P〈0.05）,but the difference of the counts taken in the second test one week later in the two groups were statistically significant（P〈0.05）.In terms of within-group comparison, the difference of the results obtained from the first and second tests in the control group were statistically significant（P〈0.05）,while the difference in the experimental group were not statistically significant（P〈0.05）. Conclusion Strengthening the pre-test quality control in biochemical tests helps significantly improve the quality and efficiency of the tests,which is of positive significance and worthy of applic
