Texas Veterinary Medical Diagnostic Laboratory
Established in 1967, the Texas Veterinary Medical Diagnostic Laboratory is one of the world’s largest and busiest veterinary diagnostics laboratories. TVMDL is composed of two full-service laboratories, in College Station and Amarillo, and two poultry laboratories in Center and Gonzales.
The TVMDL System remains centered on the following objectives: identifying disease in sick or postmortem animals; facilitating livestock commerce; serving as an animal disease surveillance system for endemic, newly emerging, and high-consequence diseases; and providing support and guidance to public health programs aimed at the control of zoonotic diseases. TVMDL is one of 12 laboratories that form the core of the National Animal Health Laboratory Network (NAHLN).
