Collecting Nasopharyngeal Swabs for Pertussis Testing
Supplies Needed:
- Dacron/Polyester Nasopharyngeal Swab (Fisher # 14-906-23, 22-209-50, 23-600-952, 23-600-955 or VWR # 95041-316). NO cotton or calcium alginate swabs will be accepted.
- Anchorage Lab Request Form
- The nasopharyngeal (NP) swab used for collecting this sample type has a fine wire or plastic shaft.
- One NP swab is collected for PCR as described below.
- Remove mucus from the patient’s nose.
- Carefully open package containing the NP swab and remove swab for sample collection.
- Tilt the patient’s head back 70 degrees.
- Gently
and slowly insert the NP swab through the nostril parallel to the
palate (not upwards) until resistance is encountered or the distance is
equivalent to that from the ear to the nostril of the patient,
indicating contact with the nasopharynx.
- Gently rub and roll the swab. Leave swab in place for several seconds to absorb secretions.
- Slowly
remove swab while rotating it. Specimens can be collected from both
sides using the same swab, but it is not necessary to collect specimens
from both sides if the NP swab is saturated with fluid from the first
collection.
- Place the NP swab back into a sterile tube.
- Clearly label the sterile tube containing the swab with patient’s name and date of birth (i.e., two identifiers).
- Complete the Anchorage Lab Request Form.
Transport:
- Place the sterile tube containing the NP swab in the specimen biohazard bag and seal. Place the completed Anchorage Lab Request Form in the outside pouch.
- Package as a Biological Substance Category B specimen and send to the Anchorage State Public Health Laboratory as soon as possible. If needed, hold the specimen at 4°C until transport. Ship at ambient temperature.
