不同检验方法在肺结核早期诊断中的应用

目的：探讨不同检验方法在肺结核患者早期诊断中的应用。方法32例肺结核患者（实验组）及30例非肺结核患者（对照组）进行分析，入院后对患者采用三种方法检测，比较三种方法检测效果。结果聚合酶链式反应（PCR）对结核杆菌的诊断阳性率68.75%高于其他方法（P＜0.05）；PCR检测假阳性率为33.33%高于其他检测方法（P＜0.05）。结论肺结核患者早期诊断时采用PCR检测效果较好，准确性更高，值得临床推广使用。

Application of different inspection methods in early diagnosis of pulmonary tuberculosis

Objective To investigate the application of different inspection methods in early diagnosis of pulmonary tuberculosis patients. Methods Analyzed clinical data of 32 cases of pulmonary tuberculosis patients（experimental group） and 30 cases of non tuberculosis patients （control group）, the patients detected by 3 kinds of methods to detect patients, compared the effect of 3 methods. Results Positive rate of polymerase chain reaction（PCR） diagnosis of tuberculosis was higher than other methods（P〈0.05）;PCR detection of false positive rate was 31.25%, which was higher than that of other detection methods（P〈0.05）. Conclusion PCR has a better effect in early diagnosis of tuberculosis with higher accuracy, so it is worthy of clinical application.
