Specimen Requirement
Nasal specimen collected with Cepheid collection device is required.
Additional Specimen Collection Information
Obtain a Cepheid sample collection device (Copan double transport swab).
- If possible, have the patient blow their nose prior to sample collection.
- Open the Cepheid collection device by peeling back the outer packaging.
- Do not separate swabs; use both swabs.
- Ask the patient to tilt his/her head back.
- Insert both dry swabs approximately 1-2 cm into one of the nostrils.
- 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.
- If the patient has a nasogastric tube, do not swab the nostril containing the tube; swab only the open nostril.
- If lubricant has recently been placed in the nostril, make sure the patient blows their nose before collection.
- If there has been recent surgery of the nose, use the nostril that was not operated upon.
- If both nostrils have had recent surgery, contact the laboratory before collecting a specimen.
- Twist off the cap of the plastic transfer tube and discard it.
- Place the swabs into the plastic transport tube.
- The swabs should be 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.
- The swabs should stay attached to the red cap at all times.
- Label the plastic transport tube with the patient name, patient identification number, date & time of collection and the initials of the nurse who collected the specimen.
- Swab specimens can be stored at room temperature for up to 24 hours.
- The swab specimen is stable up to 5 days when stored refrigerated.
