Veterinary Diagnostic Testing at CSU

​The Colorado State University Diagnostic Laboratories hold Laboratory Accreditation from the American Association of Veterinary Laboratory Diagnosticians. The laboratory is a National Animal  Health Laboratory Network (NAHLN) member in Good Standing, and is also a member of the Laboratory Response Network (LRN). View a map of the NAHLN approved laboratories.

The combined Colorado State University Veterinary Diagnostic Laboratories handle over 400,000 cases a year. VDL faculty hold over 50 positions in state and national veterinary diagnostic organizations. VDL faculty provide critical research and publish widely to protect animal and human health.

The Diagnostic Laboratories perform a wide variety of disease surveillance and investigation projects, many of which would be very expensive or impossible to do under laboratory purely conditions. The collaboration with producers or other government agencies usually involves a large “in-kind” contribution of animal procurement, care, and facilities costs.


Accessions submitted to the CSU-VDL, including carcasses, tissues and agents isolated from samples, become the property of the CSU-VDL unless other arrangements are made in writing prior to or at the time of submission.
