Clinical Laboratory Services

Clinical Diagnostic Laboratories

Welcome to the UC Davis Veterinary Clinical Diagnostic Laboratories. Our services include: Clinical Chemistry, including Urinalysis, Endocrinology, and Coagulation, Cytology, Hematology and Hematopathology, Immunology and Virology, Microbiology (Bacteriology / Mycology), and Parasitology.

While we are committed to providing the highest quality laboratory testing, during this time of the COVID-19 pandemic, our operational status will be re-evaluated daily based on available staffing.  We expect that turnaround times for all tests will be greatly affected, though we are unable to estimate exact turnaround times. This includes EPM testing, KHV testing, equine blood type & antibody screens, pNF-H, and OFA thyroid testing.

Due to campus mail delivery delays, please do not ship using USPS - ship via FedEx or UPS instead.

Thank you so much for your patience and understanding during these uncertain times. For the latest updates on coronavirus, please see the UC Davis School of Veterinary Medicine’s Coronavirus Resources Website.
