“The University of Arizona Veterinary Diagnostic Laboratory has been an integral part of our team for decades. Knowing our pathologist is available for consultation and welcomes feedback is invaluable. On countless occasions they have called to either have us expand on the history or to follow up on the case as to outcome. They are always helpful in recommending ancillary diagnostics that are indicated. We have 100% confidence in the results provided and consider the lab essential to our success."
