Instructions
NASAL SWAB is the ONLY acceptable source.

For nasal swabs:
1. Insert a swabs 1 cm into the anterior nares and gently rotate to obtain secretions. Apply slight pressure with a finger on the outside of the nose to help assure good contact between the swab and the inside of the nose. Using the same swabs, repeat for the second nares, trying not to touch anything but the inside of the nose.
2. Place in transport medium (Preferred: Liquid Stuart's medium; Also acceptable: Liquid Amies medium).

Transport Container
Submit nasal swab in Liquid Stuart's or Amies medium.

Methodology
Qualitative real-time Polymerase Chain Reaction (PCR)

Setup Schedule
Sunday - Saturday

Report Available

Clinical Significance
Staphylococcus aureus is a major nosocomial pathogen that causes a range of diseases including endocarditis, osteomyelitis, toxic shock syndrome, food poisoning, carbuncles and boils. Methicillin-resistant S. aureus (MRSA) strains were first identified in 1960’s and were related to acquisition of mecA gene. Nasal colonization with MRSA has been shown to be a significant risk factor for transmission of MRSA to other hospitalized or institutionalized patients. Colonization may also lead to self-infection. In the US today, MRSA is responsible for approximately 25-30% of nosocomial infections and reports of community-acquired MRSA are increasing, resulting in significant morbidity and mortality.

The rapid MRSA PCR is designed for direct detection of nasal MRSA colonization and is intended to aid in the prevention and control of MRSA infections in healthcare settings. Targets include the proprietary sequence of Staphylococcus chromosomal cassette (SCC) gene. Rapid MRSA PCR is not intended to guide or monitor treatment for MRSA infections. Concomitant cultures are necessary only to recover organisms for epidemiological typing or for further susceptibility testing.
