Protect Your Staff and Patients From Key Winter Viruses

Next Gen Winter Screening

Introducing the next generation WinterPLEX 4-in-1 super fast PCR assay.

A multiplex assay for the rapid measurement of Flu A, Flu B, RSV and SARS-CoV-2, all known variants.

Indicators from the southern hemisphere suggest winter virus infection rates are up 30% year on year.* Hospitals need to be ready with cost effective and efficient screening.

Designed for Optimal Performance

The WinterPLEX two-tube set-up not only allows greater sensitivity and a broader detection profile, but also enables compatibility with a range of PCR instruments. Using the assay with your current compatible laboratory system can achieve reliable results and therefore improved patient management without disruption to your workflows and routine.

Maximise Testing Efficiency

In addition to the convenience of testing for 4 winter viruses in one, WinterPLEX has standard reaction parameters to other assays in the genesig range, allowing the possibility of streamlined batching, and seamless and efficient detection of several analytes.

Enhanced Clinical Utility

Several studies have shown Flu A to have a greater level of severity (compared to Flu B), a dynamic, faster changing nature and a large host range which may indicate it can lead to future pandemics. It has also been linked to lower respiratory tract infections. WinterPLEX differentiates between Flu A and Flu B, giving clinicians the information needed to direct the required patient pathway.

Assay performance is reviewed annually and updated when necessary to ensure that it detects the current circulating strains of the virus. Following the most recent update, the three SARS- CoV-2 assays (Orf1ab, S and M) and RSV detect >99% of sequences circulating over the past year. The Flu A and Flu B assays are predicted to detect >97% of sequences circulating over the past year. This data is based on the sequences collected and uploaded to the GISAID (Global Initiative on Sharing All Influenza Data) database.
