The global veterinary infectious disease diagnostics market size was estimated at USD 2.46 billion in 2024 and is projected to reach USD 4.05 billion by 2030, growing at a CAGR of 8.93% from 2025 to 2030. This growth is primarily driven by the increasing prevalence of infectious diseases among both companion animals and livestock, along with rising pet ownership and heightened awareness of animal health and welfare. As pets are increasingly considered family members, owners are more willing to invest in advanced veterinary care, including early and accurate disease diagnosis. At the same time, the expansion of livestock farming to meet global food demand has increased the risk of disease transmission, further emphasizing the need for reliable diagnostic solutions.

Outbreaks of infectious diseases such as canine parvovirus, avian influenza, and bovine tuberculosis have significantly increased the demand for precise and timely veterinary diagnostic tools. Early detection plays a critical role in controlling disease spread, minimizing animal mortality, and preventing economic losses in the livestock sector. Additionally, accurate diagnostics support veterinarians in implementing appropriate treatment strategies and biosecurity measures, thereby safeguarding both animal and public health. Growing awareness among animal owners and producers regarding zoonotic diseases has further strengthened the adoption of veterinary infectious disease diagnostics.

Moreover, the rising prevalence of infectious diseases across companion and livestock animals continues to be a major factor propelling market growth, as it necessitates rapid and accurate disease identification to prevent outbreaks and ensure food safety. For instance, according to an article published by PoultryMed in May 2025, Brazil reported its first outbreak of highly pathogenic avian influenza (HPAI) H5N1 on a commercial poultry farm in Montenegro, located in the southern state of Rio Grande do Sul. As the world’s largest poultry exporter, Brazil holds a critical position in the global poultry trade. While previous detections of HPAI in wild birds did not significantly impact international trade, the occurrence of the virus in a commercial poultry facility raises concerns about potential trade restrictions and poses serious challenges for the country’s poultry industry, underscoring the importance of robust diagnostic systems.

Key Market Trends & Insights:

• North America led the global veterinary infectious disease diagnostics market in 2024, accounting for the largest revenue share of 38.25%. This dominance is attributed to advanced veterinary healthcare infrastructure, high pet adoption rates, strong awareness of animal health, and the widespread availability of advanced diagnostic technologies. The U.S. veterinary infectious disease diagnostics industry is expected to grow significantly over the forecast period, supported by continuous technological advancements and increasing investments in animal healthcare.
• The Asia Pacific veterinary infectious disease diagnostics market is projected to register the fastest CAGR during the forecast period. Growth in this region is driven by rising pet ownership, rapid expansion of livestock production, increasing disposable income, and improving awareness of advanced veterinary healthcare solutions. Government initiatives aimed at improving animal disease surveillance and food safety standards further support market expansion in the region.
• By product type, the consumables, reagents, and kits segment dominated the market and accounted for the largest revenue share in 2024. These products are essential for conducting accurate, efficient, and repeatable diagnostic tests across a wide range of infectious diseases. The recurring nature of consumables usage in routine testing significantly contributes to sustained revenue generation.
• By animal type, the companion animals segment held the largest revenue share in 2024, driven by high expenditure on pet healthcare and the growing demand for preventive diagnostics. However, the livestock segment is expected to grow at the fastest CAGR over the forecast period due to the increasing need for disease monitoring, herd health management, and compliance with food safety regulations.
• By technology, the immunodiagnostics segment dominated the market with a revenue share of over 49.00% in 2024. This dominance is supported by the widespread use of immunoassays due to their reliability, cost-effectiveness, and rapid turnaround time. Meanwhile, the molecular diagnostics segment is anticipated to grow at the fastest CAGR during the forecast period, driven by its high sensitivity, specificity, and ability to detect infections at early stages.
• By infection type, the bacterial infection segment accounted for the largest revenue share of over 40.0% in 2024, reflecting the high prevalence of bacterial diseases in animals and the availability of established diagnostic methods. In contrast, the viral infection segment is expected to register the fastest CAGR of over 9.57% during the forecast period, fueled by increasing incidences of viral outbreaks and the growing need for rapid and accurate viral detection.
