    Diagnostic agents refer to diagnostic reagents prepared using principles or methods such as immunology, microbiology, and molecular biology, and used in vitro for the diagnosis, detection, and epidemiological investigation of human diseases. Diagnostic agents can be divided into two categories: in vivo diagnostic reagents and in vitro diagnostic reagents. Except for the in vivo diagnostic reagents used for diagnosis, such as old tuberculin, brucellin, and Sickle toxin, most of them are in vitro diagnostic products. "Circulatory System Drugs" on Echemi includes organ function test agent, medical imaging drugs, and mainly supplies APIs for such drugs.
