Detect clinically relevant seasonal respiratory viruses

Influenza A, Influenza B, Respiratory Synctial Virus (A&B) and SARS-CoV-2 virus in a single-well multiplex qPCR test


Upfront Diagnosis

Triage seasonal respiratory testing with PlexPCR® Flu/RSV/SARS-CoV-2

Infections caused by Flu A, Flu B, RSV (A & B), and SARS-CoV-2 can all present with similar clinical symptoms. Adopt PlexPCR® Flu/RSV/SARS-CoV-2 to triage and diagnose these important seasonal respiratory viruses upfront.

  • Stay ahead of seasonal influenza that results in substantial worldwide disease burden1
  • RSV is an important inclusion. It is a common cause of respiratory infections, and the main cause of severe cases of bronchiolitis and pneumonia in infants and young children2,3
  • Confidently detect SARS-CoV-2, including current known circulating variants4


With peaks in seasonal respiratory test numbers, sample workload for laboratories can push testing capacity. Prioritising detection of common respiratory viruses with a uniform testing approach can improve efficiency and productivity.

PlexPCR® Flu/RSV/SARS-CoV-2 Workflow Solution

Combat seasonal testing surges with ease

Take advantage of our flexible workflow to achieve scalable throughput, easily adapting to seasonal test surges.

  • Maximise detection with this single-well multiplex test, simultaneously detecting by Flu A, Flu B, RSV (A & B), and SARS-CoV-2.
  • Obtain high sample throughput. Process up to 96 reactions per run and maintain clinically relevant turn-around times during peak testing season.
  • Enhance your productivity for rapid, routine diagnostics with PlexPrep® liquid handling automation.
  • Utilise provided analysis software to achieve automated result calling and simple data processing.

Affordable and Efficient

The COVID-19 pandemic and recent respiratory testing seasons have impacted laboratories with dramatic fluctuations in testing demands and staffing. Some laboratories are left with underused equipment and a drive to replace lost revenue, highlighting the need for affordable and efficient solutions.


PlexPCR® Flu/RSV/SARS-CoV-2 can help your laboratory work effectively and efficiently.

  • Upfront diagnosis, with a focussed multiplex and robust workflow, will streamline your routine testing
  • Test with your existing QuantStudio 5 instrument and avoid the expense of acquiring new systems and associated training, implementation and service contract costs.
