摘要: 目的评估中国疾病控制体系结核病实验室药物敏感性测试能力。方法国家结核病参比实验室下发30株结核杆菌至受评估的实验室,受评估实验室按照WHO推荐的罗氏培养基药物敏感性试验方法(比例法),进行药物敏感性试验,检测药物包括异烟肼(INH)、利福平(RFP)、链霉素(SM)、乙胺丁醇(EMB),并报告国家参比室,国家参比室将其结果与正确结果比对。结果 4种药物的4个评估指标分别为,符合率:INH 97%,RFP 95%,SM 89%,EMB 93%;重复性:INH 96%,RFP98%,SM 86%,EMB 94%;特异性:INH 97%,RFP 99%,SM 89%,EMB 96%;敏感性:INH 97%,RFP 65%,SM 91%,EMB 47%;各实验室4个评价指标均数比较,除敏感性差异有统计学意义外,其他4个检测值均高于85%,差异无统计学意义。结论除个别实验室在耐药检出能力上需提高外,其他参与实验室的药敏试验水平达到设定要求,INH、RFP药物检测稳定,SM和EMB需要进一步标化。
