We quantified methicillin-resistant Staphylococcus aureus (MRSA) carriage. The greater the log(10) count in samples from the nares, the greater the likelihood that other body sites had been colonized. Log(10) counts among body sites were correlated. The greatest sensitivity value (98%) was determined for the combined results from 2 sites: the nares and the groin.
