摘　　要：目的研究临床痰标本的合格率,帮助和提高患者正确留取标本的方法与认识,使患者得到真实有效的诊断和治疗。方法采用标本直接涂片、革兰染色、显微镜检查评价痰标本的质量,从而调查痰标本的合格率,观察痰涂片与痰培养感染菌分离率的吻合程度。结果患者留取痰标本涂片镜检：白细胞〉25/LP,扁平上皮细胞〈10/LP及白细胞〈25/LP,扁平上皮细胞10~25/LP者感染菌分离率明显高于白细胞〈10/LP者,扁平上皮细胞〉25/LP者,合格的痰标本涂片镜检的结果与感染菌分离结果的符合率高。结论严格把控采集时机、方法和送检时间,提高感染菌分离率,确保培养结果的准确性。Objective To study the qualified rate of clinical sputum specimen, it helps and improves the understanding of patients to take specimen, makes the patients obtain real and effective diagnosis and treatment. Methods The quality of specimens were evaluated by direct smear, Gram stain and microscopic examination, the qualified rate of sputum samples was investigated, and the degree of anastomosis with the infected bacteria was observed. Results Sputum specimen smear microscopy： WBC 〉 25/LP, SEC 〈 10/LP and WBC 〈 25/LP, the isolation rate of infected bacteria of SEC 10-25/LP was significantly higher than that of WBC 〈 10/LP, as SEC 〉 25/LP, the results of qualified smear examination are consistent with the isolation of infected bacteria. Conclusion It is important to control the acquisition time, method and inspection time ; It can improve the isolation rate of infected bacteria, and ensure the accuracy of training results.
