Abstract
An updated IDI-MRSA assay version was released to address the assay's low positive predictive value (PPV). A prospective analysis of two assay versions indicated no significant improvement in the PPV. Colonization by methicillin-resistant Staphylococcus aureus in 24% of patients would not have been detected if only nasal samples had been tested, as approved, by this molecular method.
摘要
发布了更新版的耐甲氧西林金黄色葡萄球菌（IDI-MRSA）检测方法，以解决该检测方法阳性预测值（PPV）较低的问题。对两个版本检测方法的前瞻性分析表明，PPV没有显著改善。如果仅按照批准的方法对鼻拭子样本进行这种分子检测，24%患者的耐甲氧西林金黄色葡萄球菌定植将无法被检测到。
