Nose Swab (Bacteriology, Oxford Road Campus)

Nasal colonisation with Staphylococcus aureus increases the risk of staphylococcal infections at other sites of the body such as postoperative wounds and dialysis access sites. Single organism nasal screens for Staphylococcus aureus may be requested as part of a PVL outbreak as part of a IPC investigation.

Laboratory information

Turnaround time for provisional result (working days): 2 days

Turnaround time to final result (working days): 2-3 days

Clinical information

Factors known to significantly affect the results: Special considerations to minimise deterioration

If processing is delayed, refrigeration is preferable to storage at ambient temperature. Delays of over 48hr are undesirable.
