微生物检验标本的不合格原因和控制策略分析

Analysis of Unqualified Reasons and Control Strategies of Microbiological Test Specimens

目的探讨导致微生物检验标本不合格的原因,并且研究有效措施加以控制。方法选择该疾控中心2014年5月—2016年5月获取的微生物检验标本1 000份作为该次研究对象;针对所有检验标本系列资料于临床展开回顾性分析;针对表现为不合格微生物标本所占有的百分比进行准确计算,并且对导致微生物检验标本不合格的原因加以分析,并且研究针对性的解决措施。结果在该次研究的1 000份微生物检验标本中,最终表现出样本不合格的标本239份,百分比为23.90%;不合格样本中包括水样样本、血样样本和一次性样本,其中水样样本168份,占所有不合格样本的70.29%,血样样本31份,占所有不合格样本的12.97%,一次性样本40例,占所有不合格样本的16.74%。因为采集样本过程中未规范操作、出现了送检不及时的现象以及标本污染的现象均会导致最终微生物检验标本不合格。结论存在诸多因素会造成最终微生物检验标本不合格的现象,对此在对微生物标本进行采集、标本运输以及标本检测过程中,需要做到满足要求规范,进而将出现不合格标本的概率显著降低,为后期患者疾病治疗提供准确参考依据。

Objective To study the unqualified reasons of microbiological test specimens and research the effective measures for controlling. Methods 1000 microbiological test specimens obtained in our center for disease control from May2014 to May 2016 were selected as the research objects, and microbiological test specimen data in clinic were retrospectively analyzed and the proportion of unqualified microbiological specimens was accurately calculated, and causes of unqualified microbiological test specimens were analyzed, and the targeted solutions were researched. Results In the 100 microbiological test specimens, 239 specimens were unqualified finally, accounting for 23.90%, the unqualified specimens included water specimens with 168, blood specimens with 31 and one-time specimens with 40, and the proportions of them were respectively 70.29%, 12.97% and 16.74%, and the untimely submission and polluted specimens in the specimen-collection process due to the non-standard operation could lead to the unqualified microbiological test specimens finally.Conclusion Many factors can lead to the unqualified microbiological test specimens finally, therefore, we need to satisfy the requirements and standards in the collection, transportation and test of microbiological specimen process thus obviously reducing the occurrence probability of unqualified specimens and providing accurate reference for the disease treatment of patients at the late stage.
