Diagnostic Laboratories

Penn Vet's diagnostic services group includes microbiologists, parasitologists, toxicologists and eight board-certified anatomic and clinical pathologists, in addition to residents in training, technicians, and administrative staff whose collaborative efforts ensure that samples are given the utmost attention.

Fast Turn-around Time and Assurance

In addition to a fast turnaround time, a unique collaborative environment allows for daily consultation rounds to discuss difficult cases and achieve consensus.
Each laboratory is closely aligned with Penn Vet's Veterinary Clinical Investigations Center (VCIC) where the primary focus is to implement clinical trials for client owned companion animals.

Discovery

Using the material provided by Penn's veterinary clients, more than 50 board certified veterinary pathologists have been trained. As members of a strong research environment, we take diagnostic discoveries from our laboratory and put them to practical use in veterinary medicine. For example, Penn Vet pathologists were the first to recognize the association between vaccination sites and development of sarcomas in cats. The microbiology laboratory focuses primarily on the transmission of methicillin-resistant staphylococci isolated from companion animals and their potential to be transmitted to humans.

Landmark discoveries by Penn Vet’s diagnostic services have benefited not only the animals served, their work has spilled over into the field of human medicine through many collaborations across the Penn campus and the biomedical research community.
