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

While continuing to adhere to guidance regulating social distancing and limiting public gatherings, the UC Davis VMTH Clinical Diagnostic Laboratories are maintaining normal hours of operation. Central Laboratory Receiving hours are Monday - Friday 8am - 9pm PST.

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

While we are committed to providing the highest quality laboratory testing, 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.

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.

The VMTH Clinical Diagnostic Laboratories will be closed Thursday & Friday, November 26-27, 2020, in observance of the Thanksgiving holiday. Do not ship packages for arrival on those days. We will reopen at 8am PST on Monday, November 30, 2020. Thank you so much for your attention to these details.
