What Keyu does

Zhuhai Keyu Biological Engineering Co., Ltd. (KEYU; Beijing Stock Exchange New Third Board: 870620) is a Chinese in vitro diagnostics (IVD) manufacturer founded in 2011 and headquartered in Zhuhai, Guangdong Province. The company designs, manufactures, and sells automated body-fluid analyzers — primarily for feces and urine analysis — alongside a growing portfolio of fluorescent and chemiluminescence immunoassay analyzers, reagents, and consumables. Its technology platform centers on deep-learning computer vision applied to microscopy images, enabling automated recognition of parasites, ova, protozoa, and formed elements; proprietary tomographic scanning captures multiple focal-plane images per field to support AI inference. Keyu holds 70+ patents and operates from a 25,000 m² manufacturing facility.

The company's product portfolio spans five lines: (1) Feces Analyzers (KU-F40, KU-F20, KU-F600, KU-F50, semi-automated FS-30, Parapro F30), which combine flotation, sedimentation, and automated iodine-staining methods with AI recognition; (2) Urine Analyzers (KU-2800, KU-600, KU-U200, KU-3000, KU-500), integrating dry chemistry and microscopy with digital imaging and AI-based classification; (3) Animal Feces Analyzers (HENRY PET-S30, Henvet Series Fusion Scan) targeting the veterinary segment; (4) Fluorescent Immunoassay Analyzers (FI-620, FI-650, FI-650s) using time-resolved fluorescence for fecal occult blood and calprotectin; and (5) Chemiluminescence Immunoassay Analyzers (st-1200i, st-1000i) for POCT and batch testing. All products integrate natively with LIS/HIS systems.

Revenue is generated primarily through hardware sales to hospitals and laboratories, supported by recurring revenue from proprietary consumables (reagent strips, test cards, sealed sampling cups) and after-sales technical services. Go-to-market combines direct sales in China with a channel-partner model internationally; the company distributes through 2,000+ partners across 20+ countries and maintains a 24-location after-sales service network staffed by 60+ engineers. The customer base exceeds 3,000 hospitals, including 600+ Class A tertiary hospitals and 100+ ISO 15189 accredited laboratories in China. International sales are driven by dedicated regional teams (Hindi, Thai, Portuguese markets) and active participation in exhibitions such as MEDLAB Dubai, MEDICA Germany, AACC USA, Medlab Asia, and Africa Health. Keyu also offers OEM/ODM services to other medical device companies.

Broad incumbents

• Sysmex Corporation: Global market leader in urine sediment analysis (UF-5000/4000 series) and hematology, with broader IVD menus. Keyu's direct global reference competitor in automated urinalysis, though Sysmex does not focus on fecal analyzers.
• Siemens Healthineers: Major IVD incumbent with the Atellica and ADVIA Centaur urine/chemistry/immunoassay platforms. Competes at the integrated-workflow level where Keyu's narrower fecal/urine menu is selected against.
• Roche Diagnostics: Global IVD leader offering the cobas urine strip/sediment analyzer line and broad chemistry/immunoassay menu. Indirect competitor through bundled hospital-lab workflows and a reference for Keyu's CE-marked products in EU markets.
• Mindray: Largest Chinese IVD and medical device manufacturer, with a broad urine sediment, chemistry, and immunoassay portfolio. Competes with Keyu across hospital labs domestically and increasingly in emerging markets via its global distribution network.
• Beckman Coulter (Danaher): Large IVD incumbent with DxH and AU urine/clinical chemistry analyzers, providing integrated lab platforms. Reference competitor in 15189-accredited reference labs where Keyu cites CAP-equivalent compliance as a value proposition.

Direct peers

• Dirui Industrial: Chinese listed IVD company (300033.SZ) and the most direct domestic competitor to Keyu, with a long-standing urine analyzer and chemistry product line serving Chinese hospital laboratories. Overlaps with Keyu on automated urine sediment analysis and LIS-integrated instrumentation.
• 77 Elektronika: Hungarian specialist in urine chemistry and sediment analyzers (e.g., LabUMat, UriSed), directly comparable to Keyu's KU series urine analyzers. Targets the same hospital and reference-lab customer profile across Europe, Middle East, and Latin America.
• Improve Medical Instruments: Chinese IVD manufacturer specializing in fecal and urine analyzers, closely matching Keyu's core product line. Competes head-to-head on automated microscopy-based parasite/formed-element detection for the Chinese hospital and ISO 15189 lab segment.

Emerging players

• ERBA Mannheim: European-headquartered IVD company with a broad clinical chemistry, hematology, and urine analyzer portfolio targeting emerging markets. Comparable to Keyu in distributor-led go-to-market and emerging-market regulatory footprint.
• HORIBA Medical: Specialist in hematology and clinical chemistry analyzers (ABX, Yumizen), with focused urine-sediment capability. Comparable as a mid-size IVD instrument vendor competing for hospital-lab slots outside the top-tier incumbents.
