Test Code INFMOL Influenza A, B PCR LAB4192
Test Method
Real Time Polymerase Chain Reaction (rtPCR)
Specimen Requirement
Xpert Nasopharyngeal Sample Collection Kit for Viruses
(Cepheid
#SWAB/B-100)
Additional Specimen Collection Information
The specimen should be collected as soon as possible after
the
clinical onset of disease. Highest viral titers are present
during
the acute illness. Nasal collection kit supplies are distributed
by
the hospital laboratory sites. Specimens in UTM tubes can
be
stored for up to 72 hours stored at 2-8°c. If there is a
delay
in testing, freeze the
specimens.
Hospital
Patients:
Nasal pharyngeal swab specimen:
- Collect the specimen using the Copan Floq Swab in the
collection kit. - Each swab has a label indicating “Flu PCR Nasal
Pharyngeal Swab”. - Transport the specimen to the lab as soon as possible.
- If there is a delay longer than 15 minutes in transporting
the
specimen to the lab, refrigerate the specimen and then transport on
a cold pack or wet ice within one hour of collection. - Remove the cap from the UTM tube.
- Insert swab into the utm tube.
- Break the swab shaft by bending it against the tube wall.
- Replace cap and close tightly.
- Label the specimen appropriately with two identifiers
(patient
ID number, DOB, etc.) include specimen source, date and
time of collection.
Outpatients:
Clients unable to transport nasal
pharyngeal swab specimens to the laboratory within one hour of
collection are supplied with the entire nasal collection kit.
- Collect nasal pharyngeal specimen.
- Remove cap from the UTM and insert the swab.
- Break the swab shaft by bending it against the tube wall.
- Replace the cap and close the tube tightly.
- Label the specimen appropriately with two identifiers,
patient
name and another identifier, (patient ID number, DOB, etc.) include
date and time of collection and initals of person collecting the
specimen. - Transport the tube on a cold pack to United Clinical
Laboratories as soon as possible.
