The North Carolina Veterinary Diagnostic Laboratory System (NCVDLS) System was established in 1947 by the North Carolina Department of Agriculture to assist veterinarians and producers in diagnosing diseases of livestock and poultry. It is a part of the Veterinary Division . Regulatory testing is performed as required for the import, export and interstate movement of livestock and poultry. Specimens for procedures not routinely performed by the laboratory system can be outsourced to the National Veterinary Services Laboratory in Ames, Iowa or other reference laboratories for testing. The number of laboratory accessions has steadily increased through the years and now includes a large percentage of companion animal submissions.
