Cepheid has announced the development of a next-generation test to assist global efforts in the fight against the spread of COVID-19 during the upcoming respiratory virus season. The Xpert® Xpress SARS-CoV-2/Flu/RSV four-in-one test is expected to deliver qualitative detection of SARS-CoV-2, Flu A, Flu B and RSV from a single patient sample. The test is designed for use on any of Cepheid's more than 25,000 GeneXpert® Systems placed worldwide, with results expected in as little as 35 minutes.

"Patients infected by SARS-CoV-2, Flu A, Flu B, and RSV have overlapping clinical presentations, but fundamentally different treatment and management pathways," said Dr. David Persing, MD, Ph.D., Chief Medical and Technology Officer at Cepheid. "Unlike the common cold viruses, infection with these four viruses is often associated with fever and other systemic manifestations that may be coupled with severe outcomes, especially in the elderly."

In the coming weeks, Cepheid intends to pursue the FDA's Emergency Use Authorization (EUA) pathway for regulatory authorization and make the test available globally on its cartridge-based GeneXpert Systems, which features instruments that can be configured for both near patient point-of-care and high volume laboratory testing needs.

"On March 20th, Cepheid was granted the first-ever EUA by the FDA for use in point-of-care settings for our Xpert Xpress SARS-CoV-2 test," said Cepheid President Warren Kocmond. "Since then, we have experienced unprecedented demand for this technology. Leveraging the quality design of Xpert Xpress SARS-CoV-2 and our widely utilized Xpert Xpress Flu/RSV tests, we're combining two world-class products in a single, rapid solution ahead of the upcoming flu season. This will enable our customers to have increased testing throughput on their current GeneXpert System and increase our ability to provide supply continuity for the market."

GeneXpert System

Cepheid

The GeneXpert System is a closed, self-contained, fully-integrated and automated platform that represents a paradigm shift in the automation of molecular analysis, producing accurate results in a timely manner with minimal risk of contamination. The GeneXpert System is the only system to combine on-board sample preparation with real-time PCR (polymerase chain reaction) amplification and detection functions for fully integrated and automated nucleic acid analysis. The system is designed to purify, concentrate, detect and identify targeted nucleic acid sequences thereby delivering answers directly from unprocessed samples. Modular in design, the GeneXpert System has a variety of configurations to meet the broad range of testing demands of any clinical environment.

AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.PCR and Thermal CyclingPolymerase chain reaction (PCR) kits and thermal cyclers are used for the in vitro amplification of DNA permitting subsequent analysis and experimental procedures. Explore a range of high-quality polymerase, primers and nucleotides or simplify your workflow with a PCR mastermix. Find reverse transcription PCR (RT-PCR) and cDNA synthesis kits for RNA products and libraries. Quantitatively measure the amplification of DNA with real-time PCR (qPCR) and droplet digital PCR (ddPCR) kits and systems, and discover automated PCR setup solutions to increase throughput. Alternative DNA amplification methods also include recombinase polymerase amplification (RPA) kits. Find the best PCR kits and thermal cyclers and purification equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Data AnalysisData analysis hardware and software is available to make data processing straight-forward yet powerful. Data software can be used for math and stats, technical graphing and image analysis. In addition, software is available for specific data analysis of electrophoresis, densitometry, ELISA and DNA sequencing.ImmunologyImmunological techniques measure and characterize immune responses. Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.Cellular PathologyCellular Pathology deals with the microscopic analysis of tissue samples and cells. Sample preparation and processing includes fixation, staining, sectioning and slide mounting, using equipment such microtomes and cryostats. In choosing immunohistochemistry and immunocytochemistry kits, consider chromogens, staining method, antibodies, microscopes and imaging.Biopharmaceutical AdvancesBiopharmaceutical advances follow the development of pharmaceuticals derived from biotechnology, also known as biotechnology medicines. Biopharmaceuticals may be produced from cell lines, plants, or microbial cells. Important considerations of biopharmaceutical use include application, cost, production process and purification.Clinical TrialsClinical Trials, an essential part of drug discovery process, assess the safety and effectiveness of a new medication or device in the pharmaceutical industry. Clinical Trials are a phased process (Phase 0, Phase I, Phase II, Phase III and Phase IV) which begins after initial preclinical testing.Clinical ChemistryBiochemistry (or clinical chemistry) involves the analysis of bodily fluids using chemical tests. Techniques used include HPLC, chromatography, spectroscopy, mass spectrometry, immunochemical, electrophoresis, turbidometric / spectrophotometric assay, MRI and ISE analysis. Tests are often carried out on plasma or serum but urine (urinalysis) and fecal specimens are also processed.Clinical GeneticsMolecular Genetics covers the analysis of hereditary genetic disease and chromosomal abnormalities. Genetics can be analysed using DNA, RNA, and protein microarrays, PCR, RT PCR and DNA sequencing. Genetic equipment includes genetic workstations, thermal cyclers, cooling blocks and electrophoresis products. Diagnostic kits are used for DNA / RNA extraction and purification.Clinical MicrobiologyMicrobiology is the study of microorganisms including protists, prokaryotes, fungi, and, often, viruses. Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers. Additionally, equipment is available to monitor environments for the presence of microbes and identify with microbial identification instruments.

Drug delivery is often approached via the biopharmaceutical or small molecule drug's formulation, but it may also involve medical devices or drug-device combination products. Considerations include instrumentation, software and services. FDAThe Food and Drug Association (FDA) is an agency within the U.S. Department of Health and Human Services. Among other things, it is responsible for ensuring the safety, effectiveness and quality of drugs, vaccines and other biological products, and medical devices.
