Influenza A Virus H1/H3 Subtype by PCR
Copy Utility
Follow-up test for patients with documented influenza A. Not a first-line test for the detection of suspected influenza in most clinical situations. Detect and subtype the two predominant strains of circulating influenza A (H1N1 and H3N2).
Qualitative Polymerase Chain Reaction
Sun-Sat
1-3 days
Respiratory specimen: Bronchoalveolar lavage (BAL), nasal wash, nasopharyngeal swab, or pleural fluid.
Fluid: Transfer 1 mL respiratory specimen to a sterile container. (Min: 0.5 mL) Also acceptable: Transfer to viral transport media (ARUP Supply #12884) available online through eSupply using ARUP Connect™ or contact ARUP Client Services at (800) 522-2787. Swabs: Place in viral transport media. Place each specimen in an individually sealed bag.
Refrigerated.
Specimen source required.
Ambient: 8 hours; Refrigerated: 5 days; Frozen: 2 months
This test targets the H3 and 2009-H1 hemagglutinin genes. The current circulating Influenza A strains are detected and typed (H1N1 and H3N2), however, other H1 and H3 subtypes may also be detected.
Compliance Statement B: For laboratory developed tests not using a RUO kit, and for FDA approved, cleared or 510(k) exempt assays with alterations. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.
