Rayto

Rayto is a China-based in vitro diagnostics company focused on the development, manufacturing, sales, and service of clinical diagnostic instruments, related software, and some associated reagents. The company is best known for commercial laboratory and hospital testing systems spanning clinical chemistry, chemiluminescence immunoassay, hematology, coagulation, ELISA, urinalysis, and related workflows. Its product portfolio includes analyzer families such as Chemray, Lumiray, Hemaray, RAC, Blotray, and Protray, and its systems are marketed for use in hospitals, clinics, blood banks, disease-control settings, research laboratories, and veterinary applications. Rayto appears to be a privately held, active company headquartered in Shenzhen, China, with international distribution across many countries. It is a healthcare diagnostics equipment manufacturer rather than a therapeutic drug developer, so it does not have a conventional drug pipeline or clinical-stage therapeutics portfolio.
