The Louisiana Animal Disease Diagnostic Laboratory (LADDL) is a full-service AAVLD-accredited laboratory.

Housed in the Louisiana State University’s School of Veterinary Medicine, the LADDL services the people of Louisiana and surrounding states by providing animal disease diagnostic services to agricultural and general communities in the state of Louisiana.
We conduct necessary research for the continued enhancement of the following outreach services: research development and adaptation of diagnostic tests and protocols, research and investigation of livestock and companion animal diseases impacting the health and well being of the animals and citizens of Louisiana, and research on selective diseases impacting the economics on the animal industries of Louisiana.

The LADDL operates in partnership with Louisiana State University, LSU School of Veterinary Medicine, Louisiana veterinarians, and livestock and poultry producers. We also provide support for the teaching and research programs of the LSU SVM.
