摘要 目的探讨结核分枝杆菌噬菌体生物扩增法(TB-PhaB)对结核性胸积液的诊断价值,并与结核分枝杆菌聚合酶链反应(TB-PCR)、腺苷脱氨酶(ADA)的检测方法相比较,以评估3种方法联合检测结核性胸腔积液的诊断价值和临床可行性。方法选取经过临床确诊的结核性与非结核性胸腔积液患者共120例,使用结核分枝杆菌噬菌体快速检测试剂盒对胸液进行检测,并同时进行胸液的TB-PCR和ADA检测。结果 TB-PhaB的灵敏度为49.23%,特异度为90.91%,准确度为0.701。ADA的灵敏度为83.08%,特异度为98.18%,准确度为0.906。TB-PCR的灵敏度为49.23%,特异度为81.82%,准确度为0.655。TB-PhaB的灵敏度、准确度与ADA比较差异有显著性,特异度则差异无显著性。TB-PhaB的灵敏度、特异度与TB-PCR比较差异无显著性,准确度则差异有显著性。三者的联合检测中,以TB-PhaB+ADA组合检测对结核性胸腔积液诊断价值较好。结论对结核性胸膜炎,TB-PhaB检测有一定的诊断价值;ADA检测是一项较有价值的指标;TB-PCR检测的诊断价值有限。联合试验的诊断价值以TB-PhaB+ADA为最佳。
