BD (Becton, Dickinson and Company), a leading global medical technology company, has announced a new high-throughput molecular diagnostic combination test for SARS-CoV-2 and influenza A/B, the second test available for the BD COR PX/MX system to have been CE marked to the IVD directive 98/79/EC.
The SARS-CoV-2/Flu assay for the COR system is an automated multiplexed real-time RT-PCR test to detect and differentiate SARS-CoV-2 and influenza A, and/or influenza B from a single nasal sample from patients who are showing signs of respiratory viral infection, as well as those who are asymptomatic.
“As long as the Covid-19 pandemic persists or evolves to an endemic situation, testing for the virus will remain an important public health tool,” said Celine Roger-Dalbert, vice president diagnostic assays R&D at BD. “And while last year’s flu season was relatively tame, with many areas loosening guidelines and mask guidance, this season could see a resurgence in seasonal illnesses. It is important to quickly diagnose if a patient has Covid-19 or flu, and type of flu, to inform patient management and to treat appropriately and early in the course of the disease.”
The COR MX/PX system allows 1,700 specimens to be loaded, with onboard capacity for reagents and samples that provide more than six hours of unimpeded system processing and up to 1,000 sample results in 24 hours, eliminating multiple technologist interactions currently required per shift. The instrument launched in 2021 with the CTGCTV2 molecular assay, a single test that detects the three most prevalent non-viral sexually transmitted infections (STIs) – chlamydia trachomatis (CT), neisseria gonorrhoeae (GC) and trichomonas vaginalis (TV).
“The SARS-CoV-2/Flu assay is the first delivery on our promise to continue to expand assays that can be performed in high-throughput central testing labs,” said Brooke Story, president of Integrated Diagnostic Solutions for BD. “We will continue to broaden our available tests for the COR system, including assays for other common STIs, overall women’s health and gastrointestinal infections.”
The system integrates and automates the complete molecular laboratory workflow from sample processing to diagnostic test result. The COR PX instrument focuses on sample workflow for diagnostic specimens and assays, preparing the samples by performing the appropriate pre-analytical processing steps and automatically delivering the samples to the instrument for molecular analysis. The instrument will perform the analytical steps of the SARS-CoV-2/Flu molecular assay, including extraction, amplification and detection.
The system is modular and scalable, and designed to address multiple needs within laboratories for expanding molecular testing and increasing test volumes. It is particularly well-suited to laboratories requiring high throughput for sample results, minimising staff interactions and automating labor-intensive and error-prone manual processes.
