The Indiana Animal Disease Diagnostic Laboratory at Purdue University (ADDL) serves the people of Indiana by diagnosing disease in livestock, poultry, companion animals, and wildlife, as well as providing blood testing of animals for federal disease programs.  

ADDL is under the joint jurisdiction of the Indiana Board of Animal Health and the Purdue

University Board of Trustees. It was established at Purdue University in 1945. The original ADDL building at Purdue-West Lafayette was one of the first buildings in the United States completely dedicated to veterinary diagnostic activities.

ADDL’s resources enable it to successfully meet its objective: to provide accurate and prompt diagnostic service to veterinary practitioners, animal producers, companion animal owners, wildlife conservationists, animal researchers, and state/federal regulatory officials.

To ensure the quality of our services, the laboratories voluntarily undergo accreditation

evaluation and designation.  The Purdue laboratories are currently designated full accreditation for all species through 2009 by the American Association of Veterinary Laboratory

Diagnosticians.  Four senior staff are diplomates of the American College of Veterinary

Pathologists; one is a diplomate of the European College of Veterinary Pathologists; two are  diplomates of the American College of Poultry Veterinarians; one is a member of the American Society of Microbiologists; one is a diplomate of the American Board of VeterinaryToxicology.

Various sections of the ADDL participate in proficiency tests conducted by the National Veterinary Services Laboratory and other quality control evaluations.  Because of ADDL nationally/internationally recognized facilities and staff, Indiana practitioners and animal producers can be assured of quality service.
