Influenza/RSV Panel TEM-PCR™

Test Code: 220600

Cpt Code:

87631 (x1)

Clinical Utility

The Influenza/RSV Panel detects 4 viral pathogens using TEM-PCRTM (Target Enriched Multiplex Polymerase Chain Reaction) technology - a multiplex PCR amplification technology to detect multiple targets simultaneously. Multiple target panel testing helps identify co-infections, provides physicians with valuable diagnostic insight into unknown causes of infection, reduces unnecessary antibiotic administration and hospital acquired infections, allows for molecular testing in patients with concurrent therapy, and more targeted therapy for better patient management and overall reduced hospital costs.

Procedure

Target Enriched Multiplex PCRTM diagnostic panel testing consists of three major steps: extraction, amplification and detection. The key to making TEM-PCRTM occur successfully lies in these primer mixes and how they allow the enrichment of multiple targets. The use of target-specific nested primers at low concentrations at the initial enrichment step allows high specificity of multiplexing amplification. After initial target enrichment is complete, Super Primers within the reaction carry out the exponential amplification and produce tagged PCR products for subsequent detection. The detection phase of the process is accomplished by measuring the fluorescence of special tags that are bound to the target sequences, which have been attached during amplification. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.

Specificity

The Respiratory Syncytial Viral assay detects both types A and B, however it does not distinguish between the two.

Assay Range

Qualitative. Positive, Not Detected.

Causes For Rejection

Wood shafted swab, calcium alginate swab, specimens received in trap containers, specimens beyond their acceptable length of time from collection as listed in the specimen handling, or specimen types other than those listed.

Turnaround Time

Same day (within 8 to 12 hours of receiving specimen), Monday through Saturday.

Shipping

Ship Monday through Friday. Friday shipments must be labeled for Saturday delivery. All specimens must be labeled with patient's name and collection date. A Viracor-IBT test requisition form must accompany each specimen. Multiple tests can be run on one specimen. Ship specimens FedEx Priority Overnight® to: Viracor-IBT Laboratories, 1001 NW Technology Dr, Lee's Summit, MO 64086.
