Key Points

High diagnostic accuracy was achieved with pooled samples for detecting MRSA carriage.
The Xpert MRSA NxG kit demonstrated 95% sensitivity and 99% specificity in a large patient cohort.
This approach highlights the effectiveness of pooled PCR testing in resource-limited settings.
Further research could validate these findings across different populations to confirm broader applicability.

Implication

Assessment shows 95% sensitivity and 99% specificity using pooled samples for MRSA, suggesting PCR is resource-efficient.

Abstract

We evaluated the diagnostic accuracy of two Cepheid Xpert MRSA assay generations using pooled samples from 4,519 patients to detect MRSA carriage in a low-prevalence population. High accuracy, including 95 % sensitivity and 99 % specificity was shown for the Xpert MRSA NxG kit. This supports pooled PCR as a resource-efficient method.
