About Singulex:

Singulex is an immunodiagnostics company at the forefront of Single Molecule Counting technology, a novel immunoassay technology recognized for unprecedented ultra-sensitivity in the precision measurement of biomarkers. Singulex is the developer of the Singulex Clarity system, a fully-automated, in vitro diagnostics platform powered by Single Molecule Counting technology. With up to 1000 times more sensitivity than existing technologies, Single Molecule Counting reveals the presence or absence of disease more clearly and definitively than was possible before. In 2017, Singulex filed a 510(k) pre-market notification submission with the U.S. Food and Drug Administration. The Singulex Clarity system and Singulex Clarity assay have the CE mark and are commercially available in Europe. Additional assays to detect and rule out infectious and inflammatory diseases are in development. Singulex is also developing a point-of-care platform and exploring applications beyond the clinical setting. For more information, please visit singulex.comOpens a New Window. or
