Infectious
Additional Codes
EPIC: LAB7048
Methodology
RT-PCR (Real Time Polymerase Chain Reaction) Cepheid GeneXpert
Useful for rapid detection of methicillin-resistant Staphylococcus aureus (MRSA) from nasal swabs in patients at risk for nasal colonization.
Performing Laboratory
St. Joseph Hospital
Specimen Requirements
Cepheid (COPAN) Sample Collection swabs must be used.
- Open the Cepheid Collection Device (red capped COPAN swab with perforations) by peeling back the outer packaging.
- Ask the patient to tilt his/her head back. Insert dry swabs approximately 1–2 cm into each nostril.
- Rotate the swabs against the inside of the nostril for 3 seconds. 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 nostril, trying not to touch anything but the inside of the nose.
- Remove the plastic transport tube. Twist off the tube cap and discard it. Place the swabs into the plastic transport tube. The swabs should go all the way into the tube until they rest on top of the sponge at the bottom of the tube. Make sure the red cap is on tightly. Note: the swabs should stay attached to the red cap at all times.
- Label the plastic transport tube with patient ID and send to the laboratory.
Store swab specimen at room temperature (15-30ºC) if it will be processed within 24 hours, otherwise store swab at 2-8ºC. The swab specimen is stable up to 5 days when stored at 2-8ºC.
