痰标本采集、储存及运输过程对培养结果影响的分析

目的 通过分析某市级结核病实验室痰培养数据，总结县级运送阳性痰标本至市级进行痰培养工作模式对痰培养结果的影响因素。 方法 对江苏省某市级结核病实验室2010年4月-10月痰培养数据进行分析。 结果 该实验室初诊涂阳病人痰培养共计475例，对痰标本采集、储存、运输、培养等各个环节进行分析，得出：不同送样县区（P=0.007），不同痰标本数量（P=0.008），不同送样时间间隔（P=0.037）,不同痰标本阳性级别（P=0.001）的痰培养结果均有统计学意义。 结论 由县级运送痰标本至市级进行痰培养，应在采集标本时严格按照《中国结核病防治规划实施工作指南》（以下简称《指南》）要求采集即夜晨3份痰标本，提高送检痰标本质量，尽快送检，并加强对不同县区样品采集运送人员的培训。
