The Rabies Laboratory at the Wisconsin State Laboratory of Hygiene (WSLH), located on the University of Wisconsin-Madison campus, is the only rabies diagnostic laboratory in Wisconsin. The WSLH Rabies Laboratory works closely with epidemiologists at the Wisconsin Division of Public Health (WDPH) and personnel from other state and federal agencies as part of a comprehensive rabies control program.
The WSLH Rabies Laboratory receives between 2,000 and 2,500 animal specimens from throughout Wisconsin for testing each year. Immunofluorescent tests are performed directly on samples of selected regions of the brain of the animal specimen. Additional testing of positive samples is performed to determine the type of rabies virus present.
In addition to providing diagnostic testing services, the WSLH also administers a rabies proficiency testing program for rabies laboratories throughout the U.S.

- The State Public Health Veterinarian or other assigned CDES staff will decide whether Saturday testing is warranted, based on whether someone will need to begin rabies post-exposure prophylaxis unless weekend testing is performed.
- You must provide a contact name and phone number to receive telephoned results if you request weekend testing. The contact may be a local public health department staff member or a health care provider who will contact the patient and arrange for prophylaxis, if required.
