Marshfield Labs moved from their Madison lab into the newly expanded Veterinary Emergency Service building in Middleton at the end of August 2010. Marshfield Labs is committed to the Madison area veterinary medical community by providing convenient reference lab testing that you can trust.
Marshfield Labs Veterinary Services was established in 1991 to serve the needs of veterinarians throughout Wisconsin and the Midwest. While our main lab is located in Marshfield, Wisconsin, we have expanded to include additional laboratory locations providing daily services for veterinarians and research facilities nationwide.
As part of a large medical and research institution, we maintain the same stringent standards of quality control and assurance throughout all of our laboratories. Our pathologists and laboratory staff are committed to providing service that goes beyond what is expected.
Our goal is to provide the highest quality laboratory service to you and your patients by offering:
- ACVP diplomate veterinary pathologists with extensive diagnostic experience
- A comprehensive test menu
- Accurate and timely testing at reasonable prices
- Convenient pick up through ground and air courier services
- Results when you need them online, email or via fax
Why is a stat lab important in an emergency and specialty practice?
Lab tests are an important diagnostic tool in veterinary medicine. When a pet visits our emergency clinic or our specialty center, they are often in need of more than just a routine check up. Having a Marshfield on site provides many advantages to your pets care.
- One hour turn around time
- Extensive test menu, including specialty tests
- Outstanding test accuracy and quality control
- Professionally trained lab personnel
- Shared relationship between our clinic, our referring clinics, and our clients
