目的了解、掌握某结核病实验室痰片镜检情况,从而制定有效可行的措施,提高痰检质量,尽可能发现涂阳患者。方法进行人员现场涂片、染色、镜检等比对。结果首先,痰标本是否合格以及是否挑取可疑部分直接决定阳性检出率;其次,阳性检出率还跟涂片制作的大小、厚薄、染色等方面的操作规范与否有关。结论某县结核病人涂片阳性率低,跟实验室的痰检质量有直接关系,可以以此为突破口,加强结核病实验室工作人员的技术培训,并在后期增加现场督导、质控频次,为控制结核病传播提供有力的技术保障。
Objective To understand and master the sputum microscopic examination of a tuberculosis laboratory to develop effective and feasible measures to improve the quality of sputum examination, as far as possible smear positive patients. Methods On-site smear, staining, microscopy and other comparisons. Results First of all, whether the sputum specimens pass the test and whether to pick suspicious parts of the direct determination of the positive detection rate; Second, the positive detection rate with the smear production size, thickness, staining and other aspects of the operation norms or not. Conclusion The positive rate of smear in TB patients in a county is low, which is directly related to the quality of sputum examination in the laboratory. This can be used as a breakthrough point to strengthen the technical training of tuberculosis laboratory staff and increase the frequency of site supervision and quality control Control of TB transmission provides strong technical support.
