肺结核常根据临床症状、X线胸片、痰涂片和培养诊断,而后者阳性率低。为探讨肺结核的病原学诊断方法,我院用聚合酶链式反应(PCR)检测肺结核痰中结核杆菌进行探讨。1 材料和方法 1.1 研究对象实验组60例为临床确诊的肺结核住院病人,每例取晨痰2份,共120份。对照组20例,临床诊断为支气管炎的住院或非住院患者,每例取晨痰2份,共40份。
Tuberculosis is often based on clinical symptoms, X-ray, sputum smear and culture diagnosis, while the latter has a low positive rate. To explore the etiological diagnosis of tuberculosis, our hospital with polymerase chain reaction (PCR) detection of tuberculosis sputum Mycobacterium tuberculosis to explore. 1 Materials and Methods 1.1 Subjects Experimental group 60 cases of clinically diagnosed pulmonary tuberculosis inpatients, each taking morning sputa 2, a total of 120. Control group of 20 patients were clinically diagnosed as bronchitis in hospitalized or non-hospitalized patients, each taking morning sputum 2, a total of 40 copies.
