Hefei Tianyi Institute of Biological Technology

Hefei Tianyi Institute of Biological Technology is a private China-based in vitro diagnostics and medical technology company focused on the R&D, manufacturing, and commercialization of diagnostic reagents and related instruments. The company is particularly active in transfusion safety, blood banking and supply services, vitamin testing, nutritional monitoring, and selected microbial testing applications. Its product and technology base spans microcolumn gel immunoassay, electrochemical detection, biosensors, and biochemical testing, supported by GMP-standard production lines and ISO 13485 quality management. Tianyi appears to operate as a revenue-generating commercial diagnostics business rather than a therapeutic drug developer, with products sold to hospitals and blood-service institutions across China. The company has reported a substantial domestic service footprint and a portfolio of patents and other intellectual property tied to its diagnostic platforms.
