The Michigan State University Veterinary Diagnostic Laboratory (MSU VDL), a service unit in the College of Veterinary Medicine, is a premier, full-service, fully accredited veterinary diagnostic laboratory for all species. We are the diagnostic arm of the college that provides animal health diagnostics for Michigan and beyond.

Serving livestock, poultry, horses, and wildlife as well as companion, exotic, aquatic and zoo animals, the MSU VDL is equipped to assist with the care of animals throughout every stage of their life cycle. Our comprehensive test offerings give clients easy access to routine and specialty diagnostics using the latest diagnostic technology and quality assurance methods. On average, we perform one million tests per year on approximately 180,000 cases for more than 300,000 animals.

In addition to a catalog of 700+ tests, our experts are available for consultation on cases. Our commitment to public service means that clients can often consult directly with the diagnostician responsible for their cases, further ensuring accuracy and continuity of care.

The MSU VDL is an invaluable resource in identifying, tracking, and addressing emerging animal and public health issues. Our faculty and staff work with national, state, and local officials to investigate and counter threats such as avian influenza, bovine tuberculosis, chronic wasting disease, West Nile virus, and more.
