探讨半定量TB－PCR 荧光探针诊断试剂盒的临床应用价值.方法 以双盲法对115例结核病和59例非结核病人的痰标本进行厚涂片抗酸染色检查、结核菌培养、荧光探针 TB－PCR 检查对比.结果 三种方法检测的敏感性分别为32.2%、59.1%、71.3%,荧光探针TB－PCR 法的敏感性显著高于培养法和涂片法(P＜0.01和P＜0.05).特异性分别为93.2%、91.5%、94.9%,差异无显著性.结论 半定量TB－PCR荧光探针诊断试剂盒可应用于临床结核杆菌检测.“,” Objective To evaluate the clinical application of semiquantitative PCR technique with gene-marked flourotagger probe GMFP for detecting mycobacterium tuberculosisTB. Method Thick smears of sputum from 115 patients with tuberculosis 59 patients without tuberculosis were detected by acid-fast stain culture and GMFP-PCR method and the results were compared. Results The sensitivity was 32.2% by smear 59.6% by culture and 71.3% by GMFP-PCR method respectively. The sensitivity of GMFP-PCR method was obviously higher than that of smearP<0.01 and cultureP<0.05. The specificity was 93.2% by smear 91.5% by culture and 94.9% by GMFP-PCR method respectively showing no significant difference. Conclusion The semiquantitative GMFP-TB-PCR method is an efficient way for the detection of TB. 
