Gastrointestinal Laboratory

The GI Lab at Texas A&M University provides specialized testing services to help veterinarians diagnose and treat gastrointestinal diseases in dogs and cats.

These tests may help in the management of pets with vomiting, weight loss, diarrhea, loss of appetite, or poor body condition.

All samples must be submitted by a veterinarian. Veterinary specialists in Internal Medicine certified by the American College of Veterinary Internal Medicine are available for consultation to discuss interpretation of test results with submitting veterinarians, and their implications for patient management.

We cannot give advice directly to pet owners due to licensure issues.

Important Testing Update:

Due to a shortage in native canine alpha-1-PI we had to suspend all fecal alpha-1-PI testing. We are working on purification of more protein, but at the moment we can not accept any new samples for testing – we apologize for any inconvenience this may cause! Please contact us should you have any further questions.


Shipping updates:

We are not here to receive packages on the weekends and they will sit unattended if delivered on Saturday, Sunday, or on a holiday, even if shipped using FedEx or UPS. Shipping using USPS (US Mail) is never recommended due to delays that will affect your results. The university post office may be closed anytime the university is closed.
