摘要: 目的评价荧光定量PCR技术在肺结核病诊断中的应用价值。方法采用荧光定量PCR、金胺O染色荧光镜检和培养法同时检测860例肺结核患者的痰标本,对检测结果进行比较。结果荧光定量PCR检测灵敏度可达10~100 cfu/ml,重复性好,对其他呼吸道病原体检测结果均为阴性。肺结核患者痰标本荧光定量PCR检测阳性率要高于金胺O染色荧光镜检和培养法的阳性率,差异有统计学意义(P<0.01)。结论应用荧光定量PCR方法检测结核杆菌,具有特异、灵敏、简便、快速的特点,可作为结核病诊断的方法之一。

Abstract: Objective To study clinical value of fluorescent quantitative PCR(FQ-PCR) on detection of Mycobacterium tuberculosis complex(MTB).Methods 860 sputum samples from the patients with pulmonary tuberculosis were detected by FQ-PCR,staining and culture,respectively.The sensitivity and specificity of FQ-PCR were assessed by comparing the results.Results The sensitivity of FQ-PCR reached 10~100CFU/ml.The results of other pathogens in respiratory tract were negative by FQ-PCR.The positive rate of FQ-PCR in testing ...
