Abstract

The Cepheid Xpert MRSA/SA nasal PCR assay was compared to culture for quantifying Staphylococcus aureus load from 104 nasal samples (r = 0.91, P < 0.0001). Using a bacterial load-based algorithm, the test was found able to predict the carrier state in 32 of 35 healthy volunteers (22 persistent and 13 nonpersistent carriers).
