Oklahoma Animal Disease Diagnostic Laboratory

Oklahoma Animal Disease Diagnostic Laboratory We provide vigilant, accessible, and accountable diagnostic service for Oklahoma veterinarians and animal owners.

The Oklahoma Animal Disease Diagnostic Laboratory was established in 1976 through the efforts of concerned and dedicated Oklahomans. Foremost among its early advocates was a Board of Advisors that continues to provide advice, counsel, and support for the laboratory's operations. Others who were instrumental in the establishment of the laboratory include farmers, ranchers, pet owners, veterinarians, wise and understanding legislators, and far-sighted governors. The laboratory's mission is to provide vigilant, accessible, and accountable diagnostic service for Oklahoma veterinarians and animal owners. Its goals are to help reduce Oklahoma's expensive losses to animal diseases and parasites, to reduce the incidence and threat of diseases that are transmissible from animals to man, and to provide support for the teaching and research programs of the Center for Veterinary Health Sciences. The key to our success is held in the hands of the laboratory staff - a staff that is dedicated, hard-working, productive, and ready to go the extra mile that is often required to find helpful answers for hard problems. We welcome the opportunity to serve Oklahoma and Oklahomans.

Dr. Claud Evans spent his life as a humble servant-leader who continuously championed the land-grant mission and gave back to fellow Oklahomans.

Claud served rural Oklahoma as a veterinarian, and he served on the OSU/A&M Board of Regents, including two terms as the board’s chairman. His life’s path of service and leadership inspired every life he touched.

On behalf of the entire Cowboy Family, Angela and I send our heartfelt condolences to Elayne and their entire family.
