QUANTERIX CORPORATION

Quanterix Corporation specializes in the development, maintenance, and support of ultra-sensitive immunoassay platforms for biomarker detection in biological samples, with a primary focus on the Simoa HD-X and SR-X systems. Their core capabilities center on single-molecule array (Simoa) technology, enabling the quantification of proteins and analytes at femtogram concentrations—critical for early disease detection, neurodegenerative research, and infectious disease monitoring. The contractor provides end-to-end support including instrument calibration, preventive and emergency maintenance, reagent supply, and assay development services tailored to clinical and research cohorts. Their technical expertise spans analytical laboratory instrumentation, biological sample processing, and precision diagnostics, with a distinct specialization in high-sensitivity protein detection for low-abundance biomarkers in complex matrices such as serum, CSF, and plasma. Quanterix maintains a strong and consistent relationship with the Department of Health and Human Services, delivering critical diagnostic support to NIH institutes like NICHD, and also serves the Department of Veterans Affairs with maintenance and research services using their Simoa platforms. These engagements reflect a pattern of long-term, mission-critical partnerships focused on advancing precision medicine and longitudinal health monitoring in veteran and clinical populations. The company’s industry focus is anchored in analytical laboratory instrument manufacturing and electronic equipment maintenance, with secondary work in biological product manufacturing and research services. Their market positioning is that of a niche provider of next-generation diagnostic infrastructure, serving government-funded biomedical research and clinical diagnostics programs requiring unparalleled sensitivity. Quanterix Corporation is a privately held entity based in Billerica, Massachusetts, with no federal certifications on record. Their geographic and operational footprint is centered in the U.S. biotech corridor, serving federal health and research agencies through specialized technical support and proprietary diagnostic technology.
