临床血液样本检测前不合格因素分析及应对的措施

目的：结合目前临床检验中面临的样本不合格的实际问题，分析其原因，并提出改进措施。方法：我科收集2012年4月-10月住院患者血液样本共计69398份，根据样本凝固、溶血、脂血、量不准确和其他错误，判断为不合格归类统计分析。结果：经统计不合格样本1594份，不合格率为2.3%，其中凝血264份，溶血253份，样本量不准确659份，脂血281份，其它错误137份，分别占不合格的样本的16.6%、15.9%、43.1%、17.5%、9%。结论：加强血液样本的采集、运送和处理等分析前质量控制，是检验科全面质量控制的基础环节，临床医护人员要严格执行操作规程，强化培训，提高技术水平，采取有效措施，最大限度减少不合格样本的发生，确保样本质量。

Before detection unqualified factor analysis of clinical blood sample and response measures

Objective： Combined with today＆#39;s unsatisfactory samples for clinical laboratory practical issues, analyse their causes, and propose improvement measures.Methods：Our Department collects blood samples from inpatients in April 2012-October amounted to 69,398, solidification, hemolysis and lipid based on a sample of blood, measuring inaccuracies and other errors, judged to be ineligible classified statistical analysis.Results：By the statistical samples of 1594, a failure rate of 2.3%, 264 of blood coagulation, hemolytic 253, sample sizes not accurate 659, lipid 281, other error 137, with respective shares of unqualified samples, 16.6%,15.9%, 43.1%, 9%.Conclusions：Strengthening the collection, transport and processing of blood samples prior to analysis, such as quality control, is the basic part of the total quality control of clinical laboratory, clinical staff have to obey the rules, training, improved technology, and take effective measures to minimize the occurrence of samples to ensure that samples quality.
