Quanterix

Quanterix is a life sciences company that develops an ultra-sensitive digital immunoassay platform to advance precision health for research and diagnostics. Its Simoa platform employs bead-based and planar array technologies to detect protein biomarkers at very low concentrations in blood, serum, and other fluids that are undetectable by conventional assays. This enables early disease detection, improved prognosis, and more informed treatment decisions in clinical settings and research. The company provides instruments, assay kits, LDTs and assay services, as well as specialized modules and systems such as HD-X automated immunoassay analyzer, aiming to support biomarker analysis across healthcare and life science applications.
