The Texas A&M Veterinary Medical Diagnostic Laboratory, TVMDL, offers multiple methods of detecting and identifying animal parasites. Depending on the case, animal owners may submit an animal’s feces or blood as a sample type for detection. If available, the parasite can also be submitted for identification. Texas is host to countless types of animal parasites.

It’s important animal owners are aware of the presence of parasites to determine the next steps in treatment and prevention. TVMDL’s parasite-specific tests can be used for both domestic and exotic species. Please consider scheduling a consultation with one of TVMDL’s veterinary diagnosticians to ensure the best testing option is requested.

Please note TVMDL only accepts veterinary specimens.


TVMDL tests thousands of veterinary specimens from clients across Texas, in neighboring states and around the world every business day, protecting the health of livestock, poultry, companion animals, exotic animals, racing animals and wildlife. Veterinarians, animal owners, animal industries and government agencies depend on TVMDL’s expertise for early detection and control of diseases. TVMDL also belongs to a nationwide network of laboratories that provide surge-testing, response and recovery capacity in the event of an animal disease outbreak. Over its history, TVMDL has played a critical role in recognizing and containing outbreaks of anthrax, avian influenza, chronic wasting disease, equine piroplasmosis and many other economically devastating animal diseases.

General Testing

For inquires about available tests, specimen types, test prices, or turnaround times, please refer to the TVDML test catalog. Clients may search the catalog by a test’s name or test code. The test catalog may also be accessed via the TVMDL Mobile app.


TVMDL does not see or treat animals. If you have clinical requests or need immediate assistance with an animal emergency, please contact a veterinary clinic.
