A new MRSA test that helps you detect recently emerged strains has earned the Food and Drug Administration's market approval, says manufacturer BD Diagnostics.
The BD MAX MRSA XT Assay is the company's second test that can detect MRSA strains with the mecC gene, but the first that can do so via a nasal swab. The earlier version, released in 2013, could be used only on patients about to undergo surgery.
The test eliminates false positives produced by assays that detect S. aureus strains without certain genetic features, says the company, which can lead to expensive and unnecessary isolation of patients.
MRSA strains with the mecC gene account for nearly 3% of new MRSA cases in some areas, but can't be detected by all assays.
