We prospectively investigated the diagnostic utility of the Xpert MTB/RIF (Mycobacterium tuberculosis/rifampin [RIF] resistance) assay in 20 cases with confirmed tuberculous pleural effusion. The sensitivity and specificity of the Xpert assay in pleural fluid were 25% and 100%, respectively. All cases positive by the Xpert assay were also positive by pleural fluid culture.
我们前瞻性地研究了 Xpert MTB/RIF(结核分枝杆菌/利福平[RIF]耐药)检测在 20 例确诊结核性胸腔积液中的诊断效用。Xpert 检测在胸腔积液中的灵敏度和特异性分别为 25%和 100%。Xpert 检测阳性的所有病例胸腔积液培养也均为阳性。
