INFLUENZA A and B, RAPID

MERCY TEST NAME

INFLUENZA A and B, RAPID

MERCY LAB CODE

FLU

Specimen:  

Nasal wash/aspirate.  The sample is stable 4 hours at room temperature or 24 hours refrigerated.

Nasal Swab. This is not the required specimen for testing, at Mercy lab. However if collection of a neasal wash is not possible, a nasal swab sample can be collected. The swabs used for collection CAN ONLY BE THE SWABS PROVIDED IN THE KIT.  Swabs will have to be requested from the lab, at time of collection. The specimen will have to be hand delivered, immediately after collection. Collect 2 swabs, one from each nostril. Place both back in their paper wrapper. Label the swab shafts with the patient information. Hand deliver to the lab immediately.

Comment: 

  • Test is very specimen dependent.  False negatives may be reported if the specimen is inadequate or poorly collected.
  • Immediately transport to Laboratory
  • Test differentiates between influenza A and influenza B.
  • Although testing is available whenever a diagnosis of influenza is suspected, testing for influenza is not recommended outside of the respiratory virus season or in the absence of a current outbreak due to low specificity of the test.

RL Client Comments:

  • Order using SQ test code FLU or write INFLUENZA A/B RAPID on the order form
  • Nasal washes: Send the specimen refrigerated to Mercy lab.
    Nasal swab: On campus specimens should be hand delivered to the lab immediately. Off campus specimens should be placed in viral transport media.

Performed:

Within 8 hours of collection.  Available stat.

Reference value:

Negative for Influenza A and B.

Method:

Lateral Flow Immunoassay.

CPT Code:

87804

 

 

TEST NAME

INFLUENZA  A and B, PCR

MERCY LAB CODE

MISM

Specimen:  

Any of the following sources are acceptable for testing.

M4/M5 transporters can be requested from the Microbiology Lab (Ext. 87494)

  • Nasopharyngeal Swab (Insert swab through the nostril into the nasopharynx until the tip reaches distance equivalent to that from the ear to the nostril of the patient.  Rotate swab several times, remove, and place swab in the M4/M5 transport medium.  Do not remove the swab).
  • Throat Swab (Rub the tonsils and posterior pharynx with swab.  Place the swab in the M4/M5 transport medium. Do not remove the swab).
  • Nasal Swab (Place the swab in each nostril and allow swab to remain in place for several seconds.  Place the swab in the M4/M5 transport medium.  Do not remove the swab).

Label the specimen with patient name, date and time of collection, and source.  Fill out the enclosed patient history paperwork.  Deliver the specimen and paperwork to the laboratory immediately after collection.  If there is a delay in delivery, specimens should be place in the refrigerator, at 2-80C.

 

Comment: 

 This testing should NOT be used for routine testing for influenza.  This testing should be limited to circumstances where more sensitive testing is needed (PCR), in order to help diagnose an influenza illness; usually after a negative rapid influenza but patient is still experiencing influenza like illness.  Orders will be monitored, to ensure compliance, before being referred to SHL for testing.

Performed:

At State Hygienic Laboratory, M-F

Reference value:

Negative for Influenza A and B

Method:

PCR
