Test includes:
The direct detection of nasal colonization by S. aureus (SA) staphylococcal protein (spa) gene and/or methicillin-resistant S. aureus (MRSA). Staphylococcus chromosomal cassette (SCC) gene targets to aid in the prevention and control of SA and MRSA infections in healthcare settings.
Real-time Polymerase Chain Reaction (PCR)
SA, pre-surgical screens, MRSA, MDRO, S. aureus, Methicillin resistant Staphylococcus aureus, PCR, Staph PCR, S. areus PCR, MRSA PCR, MRSA Screen, MRSA Nasal Screen, Nasal Screen, Nares Screen, Nares PCR, MRSA screen, admission, HAI, surveillance, SAURP
Clinical significance:
Nasal colonization with SA and/or MRSA has been shown to be a significant risk factor for transmission of SA and MRSA to other hospitalized or institutionalized patients. Colonization may also lead to self-infection.
