Update: Return to normal hours of operation

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

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.

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

We will continue to update our website as information becomes available. 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.
