Specimen Requirements
Specimen
Nasal swab
Volume
One swab
Minimum Volume
One swab
Container
Swab in Liquid Stuart Media
Collection
Moisten the swab with two drops (about 50 μL) sterile physiological saline or use it dry. Carefully insert the swab into the patient's nostril (the swab tip must be inserted up to 2.5 cm (1 inch) from the edge of the nares). Roll the swab five times. Insert the same swab into the second nostril and repeat sampling. Place the swab in its container. Label container and ship to the laboratory according to standard operating procedures.
Storage Instructions
Store specimens at room temperature (15°C to 25°C) for 48 hours or refrigerate (2°C to 8°C) for five days.
Causes for Rejection
Inappropriate transport or storage conditions; name discrepancy or unlabeled specimen; expired swab transport; wire-shaft swab
Test Details
Use
MRSA by NAA is a qualitative in vitro diagnostic test for the direct detection of nasal colonization by methicillin-resistant Staphylococcus aureus (MRSA) to aid in the prevention and control of MRSA infections in health care settings.
Limitations
MRSA by NAA is not intended to diagnose MRSA infections nor to guide or monitor treatment for MRSA infections. Concomitant cultures are necessary only to recover organisms for epidemiological typing or for further susceptibility testing.
Methodology
Nucleic acid amplification (NAA)
