The global companion animal diagnostics market size was valued at USD 6.35 billion in 2024 and is anticipated to reach USD 11.03 billion by 2030, advancing at a CAGR of 9.66% from 2025 to 2030. Growing pet ownership across major countries, including the United States, Brazil, and China, continues to elevate the need for advanced veterinary care. Pet owners are increasingly prioritizing early disease detection, preventive health measures, and individualized treatment strategies for their animals.

This shift is largely driven by the rising prevalence of zoonotic diseases, which are transferable from animals to humans, reinforcing the importance of strong animal health management systems. As a result, veterinary diagnostics play a more essential role in enabling early identification of illnesses, supporting timely medical interventions, and improving overall companion animal health outcomes while also strengthening public health protection. Factors such as greater spending on animal healthcare, increasing disease incidence in pets, diagnostic technology advancements, and a growing medicalization rate continue to propel market growth.

In September 2024, Zoetis introduced the Vetscan OptiCell, an AI-powered, cartridge-based hematology analyzer that delivers laboratory-grade complete blood count (CBC) diagnostics directly at the point of care. This next-generation solution improves clinical accuracy, enhances workflow efficiency, and offers a compact, user-friendly design suited for veterinary practices. With its public debut scheduled for the London Vet Show in November 2024, the innovation is expected to significantly influence market expansion.

The launch of Vetscan OptiCell is set to support faster, more reliable on-site blood analysis, enabling veterinarians to make more immediate and informed treatment decisions. Its AI-enhanced capabilities reduce dependence on external laboratory services, lowering turnaround times and operational costs. As veterinary facilities increasingly seek advanced point-of-care diagnostic systems, demand for such solutions is likely to accelerate. This development further strengthens Zoetis’ position in the veterinary diagnostics landscape and fosters greater industrywide innovation.
