UPenn breaks ground on $94 million veterinary lab at New Bolton
Bottom line
The University of Pennsylvania School of Veterinary Medicine has broken ground on a new $94 million Veterinary Diagnostic Laboratory at New Bolton Center in Kennett Square, Pennsylvania. The 63,000-square-foot, state-funded facility will bring together New Bolton Center’s Pennsylvania Animal Diagnostic Laboratory System, or PADLS, lab and the Pennsylvania Equine Toxicology Research Laboratory under one roof, expanding diagnostic testing, research, and collaboration capacity. Penn says the building will include wet labs, office space, a necropsy suite, and biosafety level 3 lab space, while Pennsylvania officials are framing the project as part of a broader investment in the state’s animal health infrastructure.

Why it matters: For veterinary professionals, the project signals more capacity for disease surveillance, toxicology, and diagnostic support in a state with a large livestock, equine, and poultry footprint. PADLS was established in 1991 to provide rapid diagnostic support for veterinarians and producers, and Pennsylvania says its four-lab system is central to food-supply protection, trade, and outbreak response. Consolidating diagnostic and equine toxicology functions at New Bolton Center could improve turnaround, coordination, and access to specialized testing for referring veterinarians across the region.

What to watch: Watch for a construction timeline, staffing plans, and how Penn and Pennsylvania define added testing capacity once the facility moves closer to opening. (penntoday.upenn.edu)
The University of Pennsylvania’s School of Veterinary Medicine has broken ground on a $94 million Veterinary Diagnostic Laboratory at New Bolton Center, its large-animal campus in Kennett Square. The 63,000-square-foot building will consolidate two existing state-supported programs, New Bolton Center’s PADLS laboratory and the Pennsylvania Equine Toxicology Research Laboratory, in what Penn and state officials describe as a major upgrade for animal health diagnostics, toxicology, and public health preparedness in Pennsylvania. (penntoday.upenn.edu)
The project lands at a moment when states are paying closer attention to veterinary diagnostic capacity, particularly around livestock disease surveillance, food-supply protection, and zoonotic risk. PADLS, established in 1991, was designed to give veterinarians and producers rapid diagnostic support across food animals, equine medicine, wildlife, aquaculture, and public health-related testing. Pennsylvania has also been expanding that network: state officials said PADLS added a fourth lab in western Pennsylvania earlier in 2026, the system’s first expansion since it was created.

Penn’s announcement and state materials add several operational details that were missing from the initial trade pickup. The new lab will house wet research labs, offices, a necropsy suite, and biosafety level 3 space, suggesting a facility built not just for routine diagnostics, but also for higher-consequence infectious disease work and modern pathology workflows. The project is sponsored by the Pennsylvania Department of Agriculture, and the state has tied it directly to support for producers, veterinarians, regulators, racing officials, and public health agencies.

The equine side matters, too. Penn’s Equine Pharmacology Laboratory says it works closely with the Pennsylvania Equine Toxicology Research Laboratory on racehorse drug testing, and a 2024 Pennsylvania legislative transcript described PETRL as one of only a small number of fully accredited U.S. labs for that work. Folding equine toxicology into a larger, modern diagnostic complex could strengthen both testing infrastructure and cross-disciplinary collaboration between toxicology, pathology, microbiology, and regulatory partners.

State and university leaders are presenting the lab as both an animal health and economic resilience investment. In the state announcement, Agriculture Secretary Russell Redding linked the project to Pennsylvania’s $132 billion agriculture industry, while Penn highlighted the laboratory’s role in serving producers, veterinarians, public health officials, and regulators. New Bolton Center already sits at the center of a high-volume large-animal clinical ecosystem, with Penn reporting more than 6,300 hospital patient visits in the past year and more than 22,400 field-service patients treated on local farms.

Why it matters: For veterinary professionals, this is less about a new building than about diagnostic throughput, biosecurity readiness, and referral support. A larger, consolidated lab can mean faster coordination between pathology, microbiology, toxicology, and necropsy services, especially when practitioners are working up herd problems, reportable disease concerns, toxic exposures, or equine regulatory cases. Because all four PADLS labs are part of the National Animal Health Laboratory Network, added capacity at New Bolton Center could also strengthen Pennsylvania’s role in broader surveillance and emergency response. (pa.gov)
There’s also a workforce and teaching angle. New Bolton Center is one of the country’s busiest academic large-animal hospitals, and Penn has emphasized the campus’s role in clinical training. While neither Penn nor the state has yet published a detailed opening date in the materials reviewed, the facility’s design and scale suggest a long-term infrastructure play: modernize specialized testing, support regulatory and agricultural stakeholders, and give veterinary clinicians and trainees access to more integrated diagnostic resources. That could be especially meaningful for practitioners across the Mid-Atlantic who rely on regional reference relationships for complex large-animal and population-health cases. (vet.upenn.edu)
What to watch: The next signals will be project milestones, any announced completion date, whether Penn details new test menus or turnaround goals, and how the state measures the lab’s impact within the newly expanded PADLS network. (penntoday.upenn.edu)
