KRONUS

KRONUS is a private U.S. immunodiagnostics company focused on specialized immunoassay reagents and in vitro diagnostic test kits for research and clinical laboratories. Founded in 1986, the company markets autoimmune and endocrine testing products used to aid in the assessment of disorders such as type 1 diabetes, thyroid autoimmunity, neuromyelitis optica spectrum disorder, myasthenia gravis, and Lambert-Eaton myasthenic syndrome. Its portfolio includes ELISA, radioimmunoassay, and indirect immunofluorescence-based assays, with a concentration in niche autoimmune serology. KRONUS appears to be a commercial-stage diagnostics supplier rather than a therapeutics developer, and it emphasizes ISO 13485:2016 quality management certification and laboratory customer support.
