Veterinary Antimicrobial Susceptibility Testing Market Size & Share Analysis - Growth Trends & Forecasts (2025 - 2030)

Global Veterinary Antimicrobial Susceptibility Testing Market Trends and Insights

Rising Concerns about Antimicrobial Resistance (AMR)

Worsening resistance patterns in food-borne and zoonotic pathogens have pushed governments to enshrine susceptibility testing in animal-health rules. The 2025 World Health Organization TrACSS survey shows 186 countries now tracking veterinary resistance trends, up from 157 in 2021, proving that AST is no longer optional. The United Kingdom’s VARSS 2023 report recorded a 43% increase in fully susceptible E. coli isolates since 2014, linking improved outcomes to mandatory testing in livestock. In contrast, a Nigerian field study found that although 89.8% of veterinarians recognize AST value, only 4.4% routinely request tests because of cost barriers.^{[2]Source: B. Adebowale et al., “Barriers to Effective Antimicrobial Resistance Management in Nigerian Livestock,” BMC Veterinary Research, biomedcentral.com} These discrepancies show a two-tier market that favors vendors able to deliver affordable services. Continued alignment of animal and human health agendas under the One-Health framework ensures AMR will remain a core growth lever for the veterinary antimicrobial susceptibility testing market during the forecast horizon.

Expanding Companion-Animal Diagnostics Spending

Millennial and Generation Z pet owners now treat routine laboratory work as preventive care, lifting practice revenues. IDEXX reported 7% year-on-year recurring revenue growth in its companion-animal diagnostics arm for Q3 2024, reflecting higher test uptake per visit. New guidelines from the American Animal Hospital Association require culture and susceptibility panels before prescribing selected antimicrobials, institutionalizing demand. Zoetis has responded by adding AI-driven urine sediment analysis to its Vetscan Imagyst platform, reducing sample-to-answer time and broadening in-clinic test menus. These innovations encourage more clinicians to confirm pathogen susceptibility instead of using empirical therapy. As emotional bonds with pets translate into a willingness to pay for advanced care, the veterinary antimicrobial susceptibility testing market enjoys a resilient revenue stream insulated from livestock-cycle volatility.

Growth of National AMR Surveillance Mandates

Regulators are moving from voluntary to compulsory monitoring. The European Union ran its first baseline survey for antimicrobial resistance in aquaculture species in 2024, creating uniform sampling and reporting rules across 27 countries.^{[3]Source: European Food Safety Authority, “EU-Wide Baseline Survey of Antimicrobial Resistance in Aquaculture Animals,” pmc.ncbi.nlm.nih.gov} In the United States, the Food and Drug Administration funded four Animal and Veterinary Innovation Centers in 2024 to fast-track resistance research and improve diagnostic capacity. Academic institutions participate as well: the University of Minnesota now coordinates a multi-country point prevalence survey that standardizes data collection for small-animal antibiotic use. Mandatory reporting requirements create baseline volumes that buffer laboratories against economic downturns and heighten barriers for suppliers lacking accredited methods. These programs also accelerate migration toward automated platforms able to process larger sample batches with traceable quality control.

Rapid Adoption of Automated AST Instruments

Short staffing in diagnostic facilities and the need for same-day results are steering budgets toward fully automated systems. Total Laboratory Automation platforms demonstrate 99% categorical agreement with conventional workflows while cutting throughput times, enabling veterinary labs to release final reports within 24 hours. When the Clinical and Laboratory Standards Institute updated fluoroquinolone breakpoints for canine isolates in 2023, labs equipped with automated micro-dilution panels adjusted cut-offs overnight, whereas users of manual disks required weeks to re-validate methods. Zoetis now bundles cloud-based AI to interpret plate images, lowering operator skill thresholds and attracting smaller clinics. Although initial capital outlays remain high, service contracts and leasing models are spreading those costs across multi-year budgets. Collectively, these factors lift automated adoption rates and reinforce long-run demand for consumables, software, and instrumentation inside the veterinary antimicrobial susceptibility testing market.

High Cost of Advanced AST Systems and Consumables

A complete mid-range automated analyzer can exceed USD 100,000 before service contracts, placing it beyond the reach of many mixed-animal clinics. Even in mature settings, Cornell University increased its 2025 fee for systemic panels to USD 35, reflecting inflation in reagent and plastic costs. The Nigerian study cited earlier revealed that 95.6% of clinicians skip AST because of client cost sensitivity despite recognizing its clinical value. This economic friction is sharper in livestock, where producers operate on thin margins and often favor empirical treatments. Subscription-based testing networks and shared laboratory hubs are emerging to pool equipment and expertise, but uptake will take time, keeping price as a short-term drag on the veterinary antimicrobial susceptibility testing market.

Skills and Awareness Gaps in Emerging Countries

Accurate susceptibility reporting depends on correct sample collection, breakpoint selection, and result interpretation. A 2025 Malawi survey showed that although 85.5% of animal-health workers possessed solid theoretical understanding of stewardship, limited access to formal guidelines restricted best-practice adoption. Laboratory audits across North America and Canada uncovered inconsistent breakpoint usage even among accredited facilities, underlining the challenge of harmonization. Industry associations recommend continuous training, yet rural regions struggle to fund such programs. Until knowledge parity improves, under-utilization will temper growth potential, especially in lower-income economies where the veterinary antimicrobial susceptibility testing market remains nascent.

Segment Analysis

By Product Type: Automated Systems Drive Innovation

Automated analyzers are the fastest-rising product category, projected to advance at 7.16% CAGR to 2030, while disks and plates retained the highest revenue share of 39.86% in 2024 because of their low unit cost and entrenched protocols. Across many developing laboratories, disk diffusion remains the default option since it requires minimal capital and allows flexible panel design. Culture media sales move in tandem, providing growth ballast as vendors launch formulations optimized for veterinary pathogens.  

Automated systems excel where throughput, traceability, and rapid turnaround justify higher fees. Vendors integrate robotics, bar coding, and AI-powered imaging that cut hands-on time and lower error rates, making them attractive for reference labs handling thousands of samples weekly. These efficiencies reinforce consumable pull-through, enlarging the installed base and anchoring the veterinary antimicrobial susceptibility testing market. As evidence of 99% agreement between total laboratory automation and manual methods gains visibility, resource-rich clinics in Asia-Pacific are jumping directly to automated platforms, bypassing incremental upgrades.
