医学临床标本细菌学检验质量控制措施探讨

Discussion on quality control in clinical laboratory of bacteriology test

目的探讨医学临床标本细菌学检验质量控制措施，以提高病原学检测的准确性。方法回顾性分析临床各科送检的细菌标本3800例，并进行统计分析。结果标本检测质量优良为1844例，质量合格为1677例，总合格率为92．7％（3521／3800）。其中各类标本合格率前三位的是：脓肿及创伤组织标本（97．8％）、血液标本（96．9％）、生殖道分泌物标本（91．9％）。标本检测不合格279例，不合格率为7．3％（279／3800）。其中无菌操作不严格87例、标本取样位置不准确74例、标本采集量太少68例、没有及时送检36例、特殊标本未进行特殊处理14例。结论严格遵守标本采集、运送操作规范，进行正确的标本采集、保存和处理是保证医学临床标本细菌学检测质量的关键。

Objective To discuss quality control in clinical laboratory of bacteriology test. Methods From 2009 to 2011, clinical isolates of bacterial samples were retrospectively analyzed. Results The eligible rate of bacterial sample was 92.7%. Abscess and trauma sample（97.8% ） ,blood sample（96.9% ） and urinary or vaginal discharges sample（91.9% ） were in the top three after the test. The unqualified rates Of bacterial sample were 7.3% （279/3800）. Conclusion Acquisition and processing of bacterial sample rightly was the key to quality assurance of bacterial sample in clinical laboratory of bacteriology test.
