Key Market Segmentations

·         The companion animal diagnostics market is segmented by product, animal, testing category, end use, and region. By product, consumables, reagents & kits led the market in 2025 because they provide accessible, flexible, and cost-effective testing options for veterinary practices. Rapid test kits, reagents, test strips, and slides can support quick disease detection without requiring highly complex equipment.

·         By animal, dogs represented the leading segment, accounting for 38.8% of the market in 2025. Rising dog ownership, increasing pet healthcare spending, pet humanization, medicalization, and greater uptake of pet insurance are contributing to this position. Meanwhile, the cats segment is expected to register the fastest growth rate from 2026 to 2030, supported by increasing cat ownership and the need for regular diagnosis of chronic conditions.

·         By testing category, clinical chemistry dominated with a 22.95% share in 2025. Molecular diagnostics, however, is anticipated to record the fastest CAGR of 11.47%, driven by its ability to provide accurate and early disease detection at the genetic level. By end use, veterinary hospitals and clinics held the highest market share, while home care settings are estimated to grow at the fastest CAGR in the coming years.

Geographic Highlights

·         North America dominated the companion animal diagnostics market in 2025, holding a revenue share of 37.91%. Rising pet ownership, higher veterinary healthcare expenditure, and increasing adoption of preventive and precision medicine are supporting regional growth. The U.S. accounted for the highest market share within North America. Europe is also benefiting from high pet ownership, established veterinary infrastructure, animal health regulations, and increasing awareness of early disease detection.

·         Asia Pacific is expected to experience significant growth during the forecast period.

India is also witnessing notable growth as awareness of preventive animal healthcare and PCR-based diagnostic technologies increases. Latin America and the Middle East & Africa are benefiting from expanding veterinary infrastructure, increasing pet ownership, and rising spending on companion animal health.

Primary Market Drivers & Trends

The Shift to In-House Testing

Veterinary practices are increasingly adopting point-of-care and in-clinic diagnostic solutions because faster testing can support quicker treatment decisions. Portable analyzers and rapid diagnostic kits reduce dependence on outsourced laboratory services and improve workflow efficiency.

AI Integration

AI is becoming an important technology trend in veterinary diagnostics. AI-powered imaging and diagnostic platforms can improve accuracy and workflow efficiency. The introduction of Zoetis' Vetscan OptiCell, an AI-powered cartridge-based hematology analyzer, demonstrates the industry's movement toward laboratory-grade results directly at the point of care.

The Consumables Annuity Model

The strong position of consumables, reagents & kits highlights the recurring demand generated by diagnostic testing. Unlike major instruments that require significant upfront investment, consumables can be purchased and used repeatedly across routine testing activities, supporting continued market demand.
