Verification of the IDI-MRSA assay for detecting methicillin-resistant Staphylococcus aureus in diverse specimen types in a core clinical laboratory setting.

The IDI-MRSA assay has a sensitivity of 96% and a specificity of 96% when used to screen patients at extranasal sites. This verification study used previously unverified swabs and was undertaken in a core medical laboratory using nonmicrobiology technologists trained in sample processing, molecular laboratory work flow, and PCR practice.

A 24-hour screening protocol for identification of vancomycin-resistant Enterococcus faecium.

We describe a 24-h protocol for the identification of patients who are positive for vancomycin-resistant Enterococcus faecium (VRE), using stool and rectal swab samples and VRE screening broth, automated DNA extraction, and real-time PCR for vanA and vanB genes. Compared to conventional screening methods, this protocol had a high sensitivity and specificity and a negative predictive value.
