Analysis on 6726 cases of pulmonary tuberculosis patients′ sputum

目的:探讨基层检验室如何提高痰涂片检查阳性率的具体做法。方法:采用直接厚涂片萋-尼氏抗酸染色法,并对2001年-2008年间6726例肺结核病人的痰检结果情况和具体操作进行回顾性分析总结和统计学处理。结果:2001年到2005年涂片阳性率逐年提高;脓性痰阳性率>血性痰阳性率>黏液痰阳性率>水样痰阳性率;晨痰阳性率>夜间痰阳性率>即时痰阳性率;查痰次数阳性率3次以上者>3次者>2次者>1次者;观察300视野阳性率>观察200视野>观察100视野。结论:合格痰标本、多次送检、晨痰、镜检视野数300以上和严格做好实验室质量控制是提高痰涂片检查阳性率的关键。
