Biopsy and Necropsy Services

The Department of Veterinary Pathology provides diagnostic surgical pathology service to the Veterinary Medical Center and we offer the same service to veterinary practitioners. Necropsy services also are available. Our staff includes seven ACVP board-certified veterinary anatomic pathologists and three histotechnologists. Our goal is to provide the highest quality diagnostic service to support the professional services of veterinarians and researchers.

What services do we provide?

We provide veterinary diagnostic histopathology service for biopsies submitted to us, including tumor diagnosis and dermatohistopathology.   

Our response goal is to fax or e-mail a written report to our clients within 24 hours of receiving a specimen. Specimens requiring decalcification or special stains will usually require additional time.
