The global veterinary reference laboratory market is expanding as veterinarians, pet owners, livestock producers, and public health organizations increasingly depend on advanced laboratory testing for accurate animal disease diagnosis. Veterinary reference laboratories provide specialized and high-complexity testing that may not be available at individual veterinary clinics. Their services include clinical pathology, molecular diagnostics, parasitology, histopathology, immunodiagnostics, and other specialized testing.
According to Grand View Research, the global veterinary reference laboratory market was valued at USD 5.4 billion in 2025 and is estimated to reach USD 5.9 billion in 2026. The market is projected to reach USD 12.1 billion by 2033, registering a CAGR of 10.9% from 2026 to 2033. North America held the largest regional share in 2025, while Asia Pacific is expected to record the fastest growth during the forecast period.
The veterinary reference laboratory market is benefiting from increasing awareness of early disease detection in animals. Pet owners are becoming more willing to invest in preventive healthcare and advanced diagnostic testing, particularly for older animals and pets affected by chronic diseases.
The market is expected to more than double between 2025 and 2033. Increasing demand for specialized diagnostics, laboratory network expansion, and investments in advanced testing infrastructure are supporting this growth. Reference laboratories also play an important role in livestock disease surveillance, food safety, and outbreak monitoring.

Regional Hub Performance
- North America was the largest regional market in 2025, accounting for approximately 5% of global revenue. The region benefits from high pet ownership, strong spending on veterinary healthcare, extensive referral networks, advanced laboratory automation, and widespread access to veterinary specialists. The U.S. represents the largest country-level market in the region.
- The U.S. veterinary reference laboratory market generated approximately USD 1.67 billion in revenue in 2025 and is projected to reach around USD 3.55 billion by 2033. Demand is supported by veterinary hospitals and specialty clinics that rely on reference laboratories for oncology, endocrine, infectious disease, and other complex testing.
- Asia Pacific is expected to register the fastest growth during the forecast period. Rising pet ownership, increasing veterinary healthcare expenditure, growing livestock production, and improving diagnostic infrastructure are creating new opportunities across China, India, Japan, South Korea, and Australia.
- Europe represents another established market, supported by advanced veterinary healthcare systems, disease surveillance programs, and growing awareness of preventive animal healthcare. Latin America and the Middle East and Africa also offer opportunities as veterinary laboratory infrastructure continues to develop.
Pinpoint Key Market Drivers
One of the strongest drivers is the rising burden of zoonotic and emerging infectious diseases. Diseases that can move between animals and humans create significant public health concerns and increase the need for accurate laboratory testing and surveillance.
Veterinary reference laboratories are important components of the One Health approach because they support monitoring of animal diseases that can potentially affect human populations. Increased interaction among humans, livestock, wildlife, and companion animals is further increasing the importance of disease surveillance.
Growing pet ownership is another major factor. Pet owners are increasingly seeking preventive health checks and advanced diagnostic services for companion animals. Reference laboratories can perform complex molecular tests, pathology examinations, and infectious disease panels that may not be available at smaller clinics.
Commercial livestock farming is also supporting demand. Producers increasingly use laboratory testing to monitor herd health, detect infectious diseases, reduce mortality, and improve productivity. Production animals are expected to represent one of the fastest-growing animal segments from 2026 to 2033.

Analyze Segment Metrics
By animal type, companion animals held the largest market share of 64.2% in 2025. Dogs, cats, horses, and other companion animals require diagnostic testing for chronic diseases, cancer, infections, endocrine disorders, and age-related conditions. Increasing pet insurance adoption and preventive screening are further supporting testing demand.
The production animals segment is expected to grow rapidly as commercial livestock operations increase testing frequency. Poultry, cattle, pigs, sheep, and goats require regular disease monitoring, especially in export-oriented markets and regions with large-scale farming operations.
By technology, clinical chemistry held the largest market share in 2025. Clinical chemistry tests are widely used for evaluating metabolic functions and organ health. Automated analyzers allow laboratories to process large numbers of samples while maintaining consistent testing standards.
The immunodiagnostics segment is expected to experience strong growth as demand increases for antigen and antibody testing related to infectious and immune-mediated diseases.
By application, clinical pathology was the leading segment in 2025. It includes laboratory-based evaluation of blood, tissues, and other biological samples to support diagnosis and disease monitoring.
