多种临床标本微生物检验阳性率结果的比较分析

Comparative analysis on positive rate results of microbial test in multiple clinical samples

目的分析多种临床标本微生物检验的阳性率及其影响因素,提高临床检验水平。方法参照微生物标本检验的相关要求和标准进行检测,严格控制检测质量,以提高检测结果的准确性。结果 2015年血液标本、呼吸道标本及尿液标本的阳性率高于2014年,其阳性率差异有统计学意义(P<0.05);2个时间段痰液标本阳性率差异无统计学意义(P>0.05);影响标本阳性率的因素包括标本采集不规范、标本运送与接收不规范及检验医师技术水平问题等。结论不同时间段的临床标本,其微生物检验的阳性率不同。通过对比分析,找出其影响因素并提出相应的改进措施,可提高临床检验水平。

Objective To analyze the positive rates of the microbial test in multiple clinical specimens and their influencing factors in order to improve the level of clinical testing.Methods According to the relevant requirements and standards of microbial specimen inspection,the test quality was strictly controlled in order to improve the accuracy of detection results.Results The positive rates of blood,respiratory tract and urine specimens in 2015 were higher than that in 2014,the difference was statistically significant（P〈0.05）;the positive rate difference of sputum specimens had no statistical difference between these two time periods（P〈0.05）.The factors influencing the positive rate of the specimens included the non-standard specimen collection,non-standard specimen transporting,non-standard specimen receiving,laboratory physician′s technical level,etc.Conclusion The clinical specimens at different time periods have different positive rate of microbial test.Finding the influencing factors by the comparative analysis and proposing the corresponding improvement measures can increase the level of clinical laboratory detections.
