Viro-Plex Influenza RT-PCR Kit 2.0

Detect and Differentiate inf. (A, B, and C)

The ViroGene Infl. A/B/C Kit is a multiplex reverse transcription–real-time polymerase chain reaction (RT-qPCR) in vitro diagnostic test for the separate qualitative detection and identification of influenza A and/or influenza B virus RNA and influenza C RNA purified from human nasal swab specimens.

The ViroGene Infl. A/B/C Kit is intended for use as an aid in the differential diagnosis of viral upper respiratory tract infection in symptomatic patients when used in conjunction with other clinical and laboratory findings.

• Dual Probe Assay
  The highly mutable nature of pathogens often proves challenging in molecular assay design. Traditional qPCR assays are designed so that a single primer and probe set targets one location within the pathogen genome. However, these single-target assays often prove inadequate to detect and quantify viral targets. Sequence polymorphisms in the assay target region can cause impaired primer or probe binding, which may result in significant under-quantification or a false negative result. To eliminate this possibility, ViroGene Influenza A virus, Influenza B virus, and Influenza C RT-qPCR assay targets two regions within the pathogen genome, utilizing unique primer and probe sets for each target site. The driving principle behind our multiple-target assay design is that when a polymorphism occurs in one assay target, the additional sets of primers and probes for the alternate target region will still detect and accurately quantify the pathogen and thus reduces the likelihood of under-quantification or a false negative result.
  Two specific regions in the M gene and NP gene for the Influenza A virus
  Two specific regions in the HA gene for the Influenza B virus
  Two specific regions in the M gene for Influenza C virus.
