摘要
利用聚合酶链反应(PCR)对135例多类临床标本(痰、胸水及尿等)进行了检测。临床疑诊为结核病者105例,其中18例结核杆菌涂片阳性,PCR检测均为阳性;87例结核杆菌涂片阴性的标本,57例PCR检测阳性,总阳性率为71.4%。对照的30例非结核病的标本则无阳性。本研究结果表明,PCR在敏感性,特异性方面均优于传统的结核病诊断方法。它简捷、易行、直观,尤其适用于结核病的早期、快速诊断。
PCR technique was used to detect the repetitive DNA sequences of Mycobacterium tu-berculosis in various clinical specimens of patients with tuberculosis. The amplification proto-col gave positve results in all of eighteen cases positive by smar and in 57 of 87 cases negativeby smear. The total positive rate detected by PCR wsa 71.4%and o in 30 controls.The re-sults shoued PCR was more sensitiv and specific than conventional methods in dete- cting My-cobacterium tuberculosis.It is simple,easy to perform and directly perceived by vision,espe-cially suitable in early and rapid diagnosis of tuberculosis.
