The Wisconsin Veterinary Diagnostic Laboratory (WVDL) is a core laboratory in the National Animal Health Laboratory Network (NAHLN) and is accredited by the American Association of Veterinary Laboratory Diagnosticians (AAVLD). The diagnostic laboratory in Madison was built in 2007 and is located on the University of Wisconsin-Madison campus.  The Barron laboratory was built in 1991 and serves northwest Wisconsin.

 The WVDL has established a reputation for excellence in our work with the dairy and bull stud industries, which account for almost half of the agricultural industry’s 88 billion dollar annual contribution to Wisconsin’s economy. We are also nationally recognized for our diagnostics for emerging infectious diseases such as transmissible spongiform encephalopathies.  Our Barron laboratory play an important role in the National Poultry Improvement Program (NPIP) through is service to the poultry industry.

Dr. Phil Bochsler was named laboratory director in July of 2015, replacing interim director, Dr. Pete Vanderloo who retired, and departing previous director, Dr. Thomas McKenna.  The WVDL administration works under the direction of a board of directors, appointed by the Governor of the State of Wisconsin, and some ex-officio members from the University of Wisconsin and USDA. 

As part of the University of Wisconsin-Madison the WVDL is a strong contributor to the Wisconsin Idea, which is a century-old philosophy promoting outreach to the state, nation, and now worldwide.  Please visit us at for more information.
