Abstract

This study demonstrates the excellent diagnostic accuracy of the Xpert MTB/RIF test in patients with tuberculous lymphadenitis. The test sensitivity and specificity were 96.7% (95% confidence interval [CI], 86.6 to 100%) and 88.9% (95% CI, 69.6 to 100%), respectively, and it correctly identified 6/6 (100%) of the cytology smear-negative/culture-positive cases and 1 of 2 (50%) rifampin-resistant cases.

摘要

本研究表明 Xpert MTB/RIF 试验在结核性淋巴结炎患者中的诊断准确性极佳。该试验的敏感性和特异性分别为 96.7%(95%置信区间[CI],86.6 至 100%)和 88.9%(95%CI,69.6 至 100%),它正确识别了 6/6(100%)例细胞学涂片阴性/培养阳性病例和 2 例利福平耐药病例中的 1 例(50%)。
