About Us

Indiana Animal Disease Diagnostic Laboratory

With state-of-the-art equipment in the hands of highly trained and dedicated staff, we provide vital veterinary diagnostic testing to Indiana and the rest of the United States through diagnosis of diseases, discovery of new knowledge and dissemination of that knowledge.

The Indiana Animal Disease Diagnostic Laboratory (ADDL) and HEEKE Laboratory are focused on helping Indiana veterinarians, animal health officials, livestock producers and animal owners in protecting the health of the animal population by providing prompt, accurate, and reliable diagnoses of animal diseases, including those that may affect the human population. The ADDL is fully accredited by the American Association of Veterinary Laboratory Diagnosticians (AAVLD) and serves as the official diagnostic laboratory for the State of Indiana.

Through our extensive engagement mission, the ADDL serves as a member of the USDA National Animal Health Laboratory Network (NAHLN) and the FDA Food Emergency Response Network (FERN). The ADDL also serves a critical role in supporting the teaching programs in the College of Veterinary Medicine directed toward professional students, veterinary technology students, and graduate students and residents.
