Abstract
A preclinical evaluation was conducted to evaluate the performance of the Cepheid Xpert assay on 135 lower respiratory tract secretions for detection of methicillin-resistant Staphylococcus aureus and S. aureus. Compared with the quantitative culture, the sensitivity, specificity, and positive and negative predictive values were 99.0%, 72.2%, 90.7%, and 96.3%, respectively.
摘要
进行了一项临床前评估，以评估 Cepheid Xpert 检测方法在 135 份下呼吸道分泌物中检测耐甲氧西林金黄色葡萄球菌和金黄色葡萄球菌的性能。与定量培养相比，该方法的敏感性、特异性、阳性预测值和阴性预测值分别为 99.0%、72.2%、90.7%和 96.3%。
