What we do
Penn Vet offers diagnostic laboratory services to referring veterinarians for their patients. Our sections encompass anatomic pathology, clinical pathology and cytology, microbiology, and parasitology.
Precise diagnosis is imperative in determining successful treatment protocols and providing the highest-level of animal care, whether you are an animal owner, caretaker, or a referring veterinarian. For that reason, Penn Vet’s cross-disciplinary team of specialized, board- certified faculty, clinicians, residents, technicians, and knowledgeable administrative staff are here to assist with all of your diagnostic testing needs. We provide consultations, inter-laboratory collaboration, and a cooperative approach to maximize your diagnostic capabilities.
