# Changqi Biotech > Changqi Biotech (SuZhou) Co., Ltd. is a Shanghai-based veterinary molecular diagnostics company that builds fully automated, ultra-multiplex point-of-care testing platforms for pets, combining proprietary isothermal amplification with microfluidic chip technology to deliver PCR-level accuracy in 5-15 minutes without a laboratory or skilled operator. Founded by postdoctoral researchers from Harvard University and doctoral supervisors from Shanghai Jiao Tong University, with R&D underway since 2020, the company developed China's first fully automated isothermal microfluidic system and now markets three veterinary diagnostic lines - the Mini Dx1 Analyzer, the Mini Plex4 System, and the CQ2000 Solution - supported by in-house reagent and device manufacturing, closed-loop partnerships with JD Health and New Ruipeng, and global distribution and OEM partnership programs. Headquarters and contact point: 795 Kangwei Road, Pudong New Area, Shanghai, China; phone +86 19946200082; email shaowenjun@cqgene.com.cn. Core technology is a proprietary constant-temperature (isothermal) amplification chemistry on a microfluidic chip, positioned as faster than PCR and far more accurate than antigen strips, with detection sensitivity down to 1-10 copies and ultra-multiplex pathogen identification on a single automated chip; the workflow is a fully automated 'sample-to-result' process requiring no professional skills (lab-free POCT). Product coverage consists of three named platforms: Mini Dx1 Analyzer, Mini Plex4 System, and CQ2000 Solution, grouped on the site as the Veterinary Diagnostic Series. Commercial terms stated on the contact page: equipment MOQ is only 1 unit, reagent MOQ starts at 3 boxes (30 tests), no free samples are offered (a single device purchase is recommended for evaluation), goods are typically dispatched within 2 weeks after receipt of full payment, freight and customs clearance are paid by the buyer, and tiered discounts apply to large orders. The site targets veterinarians, pet owners, and overseas distributors/OEM partners; contact form submissions route to a thank-you confirmation page and the site states a 24-hour response time for overseas inquiries. ## Veterinary Diagnostic Products - [Veterinary Diagnostic Series Overview](https://www.cqbiotech.net/product.html): Presents the company's veterinary diagnostic instrument lineup - the Mini Dx1 Analyzer, Mini Plex4 System, and CQ2000 Solution - built on the world's first fully automated isothermal amplification technology for pets.
