TVMDL tests hundreds of specimens from clients across Texas, in neighboring states, and around the world every business day. It protects the state’s $11.4 billion livestock industry as well as poultry, companion animals, exotic animals, racing animals, and wildlife.

As one of the busiest diagnostic laboratories in the nation, TVMDL delivers accurate and timely test results that are essential for early detection and control of disease — including more than 16,000 tests annually to detect high-consequence pathogens. TVMDL’s diagnostic services make a critical contribution to the One Health/One Medicine approach to protecting public health. Every day, veterinarians, animal owners, animal industries, and government agencies depend on TVMDL’s globally recognized expertise.

Accredited by the American Association of Veterinary Laboratory Diagnosticians, TVMDL is among the 12 core laboratories in the National Animal Health Laboratory Network, designed to provide a nationwide surge-testing, response, and recovery capacity in the event of an animal disease outbreak. Staffed with more than 25 veterinarians, TVMDL provides clients with professional expertise and consultations to help solve difficult cases, and it develops and validates new diagnostic testing technologies and platforms.

TVMDL’s virology section was the world’s first to isolate canine parvovirus, and its pathology department was the first to recognize that unusual liver lesions in dogs are caused by aflatoxin contamination of corn-based dog food. It was one of the nation’s first laboratories to alert veterinarians and federal agencies to the presence of melamine in companion animal food. This resulted in a national reevaluation of the animal food inspection process. TVMDL has also played critical roles in recognizing and containing outbreaks of anthrax, avian influenza, and equine piroplasmosis.

TVMDL comprises two full-service laboratories, in College Station and Amarillo, and two poultry laboratories, in Center and Gonzales.
