The Oklahoma Animal Disease Diagnostic Laboratory (OADDL) promotes the overall well-being of animal health through veterinary diagnostic testing, instruction of professional students, and research in diseases of economic importance to Oklahoma and beyond.

Message to Veterinarians, Animal Owners and Producers

The professional staff at OADDL works closely with recognized experts in OSU’s College of Veterinary Medicine, Boren Veterinary Medical Hospital and the National Center for Veterinary Parasitology to ensure that we provide contemporary, state-of-the-art veterinary diagnostics.  We are firmly committed to providing high quality, reliable and timely service to you.

At OADDL, we make every effort to charge reasonable fees for our diagnostic services and to avoid hidden fees.  Funding provided by the State of Oklahoma helps offset a portion of the expenses associated with operating OADDL. Please refer to the Fee Schedule outlined on our website for current testing fees.

We are also actively involved in client outreach and education.  Each year we have exhibitor booths at several regional and state meetings.  We also publish a quarterly electronic Newsletter that contains information on current diseases in Oklahoma, updates from OADDL and educational articles. You can access current and previous issues of our Newsletter via our website, and we encourage you to sign up to receive the four issues each year.

We welcome your input and feedback.  At OADDL, we understand the privilege and responsibility of serving animal interests in Oklahoma.
