Detect COVID-19 causative coronavirus, SARS-CoV-2

Multiplex RT-qPCR test with dual targets
(RdRp/ORF1ab) and RNA-based internal
control in a single-well


Scalable solution supporting surge capacity

Why use PlexPCR® SARS-CoV-2?

The COVID-19 pandemic has impacted testing laboratories globally. Increased testing demands, disruptions in supply, or fluctuations in staffing due to self-isolation practices all have an effect on laboratory efficiency.

PlexPCR® SARS-CoV-2 can help your laboratory work effectively.

  • Security of supply with PlexPCR® – our unique technology de-couples the detection probe from the target sequence. We routinely produce and stockpile large volumes of test reagents to support high volume ordering fluctuations, ensuring no interruptions to your daily laboratory testing.
  • Clinically relevant turnaround times – conserved dual target sequence not impacted by current circulating variants,§ eliminating the need for repeat or confirmation testing by sequencing.
  • Streamlined workflow – compatible with robotic liquid handlers including SpeeDx PlexPrep®an automated and intuitive instrument that alleviates laboratory staffing pressures or constraints.

§Monthly reports on sequence alignment are available on request.


PlexPCR® SARS-CoV-2 workflow solution

Automation compatible workflow to maintain clinically relevant turnaround times. Includes license free, validated SpeeDx analysis software for automated result calling and simple, simultaneous data processing of large sample numbers.

  • Scalable throughput for surge testing – easily adapt to local testing demands caused by a sudden surge in suspected COVID-19 cases.
  • Flexibility in the laboratory – scale throughput up or down from 480 to 1920 samples in an 8hr shift with automated software analysis and PlexPrep® liquid handler robotics*

* compatible with other liquid handlers, throughput may vary.

Confidence in your results.

As SARS-CoV-2 continues to mutate, giving rise to variants potentially impacting diagnostic testing, laboratories need continued confidence in the results they are reporting. We routinely monitor the performance of our PlexPCR® SARS-CoV-2 assay against emerging variants to ensure you can continue to report patient test data with no hesitation.§

  • Routine in silico analysis of primer sets against a database of all available SARS-CoV-2 sequences – in accordance with global government organisation recommendations, including Medicine & Healthcare products Regulatory Agency (MHRA)

Publications & Media

We are committed to supporting continued scientific discovery and generation of clinically relevant data. Collaborations with key researchers and clinicians around the globe help us improve diagnostics and address urgent clinical needs.

Monitoring the Variants of SARS-CoV-2

In silico monitoring of the PlexPCR® SARS-CoV-2 assay inclusivity is performed monthly, with the aim to ensure new variants of the SARS-CoV-2 virus that emerge can be detected. Focused analysis is also performed on Variants of Concern (VOC) or variants of interest.
