Jiuhekit develops in-vitro diagnostic solutions for international B2B customers, including Rapid Drug Test products for preliminary screening applications. Depending on the selected configuration, products may use urine or other appropriate specimens and support single or multi-panel screening according to their intended use. Rapid Drug Test formats are designed around controlled sample application, reagent interaction, and result interpretation following product instructions. Some workflows can provide preliminary results within approximately 5–10 minutes, helping organizations manage scheduled screening efficiently. Jiuhekit supports product development, manufacturing, quality management, packaging, and international cooperation. For example, an occupational health provider processing 50 specimens can organize rapid screening in batches while referring presumptive positive findings for appropriate confirmation. This practical model combines operational convenience with responsible testing procedures for distributors, clinics, and workplace programs.
