Beckman Coulter expands infectious disease serology on the DxI 9000 Immunoassay Analyzer

Danaher

Innovations aim to support earlier infectious disease detection through sensitive and efficient serology testing

2 Sept 2026

Beckman Coulter Diagnostics, a Danaher operating company, is expanding high-sensitivity infectious disease serology testing on the DxI 9000 Immunoassay Analyzer.

Infectious disease testing continues to evolve as laboratories respond to rising test volumes and expanding screening recommendations. More than one million curable sexually transmitted infections are acquired every day worldwide among people aged 15 to 49, with most infections remaining asymptomatic. This reinforces the importance of sensitive laboratory testing that can support timely detection and informed clinical decision-making¹.

Beckman Coulter’s growing Access infectious disease serology portfolio supports testing for HIV, syphilis, viral hepatitis, and other infectious diseases on the high-throughput DxI 9000 platform. The expanding assay menu is designed to help laboratories respond to changing clinical needs while maintaining efficient immunoassay workflows².

A key component is the fourth-generation Access HIV Ag/Ab combo assay, which detects and differentiates HIV-1 p24 antigen and HIV-1/HIV-2 antibodies. Combining antigen and antibody detection supports the identification of both early and established HIV infection, providing laboratories with timely information for subsequent clinical decision-making³.

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 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.

Effective detection, prevention, and treatment are crucial to control outbreaks and improve public health. Diagnostic tools, vaccines, and antimicrobial treatments are essential components of managing these diseases. Research into emerging pathogens and resistance patterns continues to evolve. Browse our peer-reviewed product directory to find the best diagnostic tools, prevention solutions, and treatment options; compare products, read customer reviews, and get pricing directly from manufacturers.HIV and AIDSBlood tests are the most common way to identify and monitor HIV and AIDS. Current methods include ELISA, Western blot, RT-PCR viral load and CD4/8 testing. Areas for development include point-of-care assays for use in developing countries, and self-testing ‘at home’ HIV kits.ImmunoassayImmunoassays are laboratory tests that utilize antibody-antigen interactions to detect specific substances. They are widely used in diagnostics for detecting diseases, drug testing, and environmental monitoring. These assays offer rapid, sensitive, and precise detection of biomarkers, making them invaluable in clinical and research labs.
