Aspirus Reference Laboratory

Aspirus Reference Laboratory (ARL) is a state-of-the-art diagnostic testing facility located in Wausau, WI. We serve Aspirus Wausau Hospital and all other numerous referring hospitals, clinics, and specialty medical care practices both within the Aspirus network as well as out-of-network hospitals and providers, long-term care facilities, assisted living facilities, and visiting nurse associations in Central Wisconsin and the UP of Michigan.

Operating 24 hours a day, seven days a week, we offer comprehensive test menus in chemistry, coagulation, flow cytometry, hematology, immunology, microbiology, transfusion services, and urinalysis. We perform more than one million billable routine and esoteric tests annually through inpatient, outpatient, and outreach services.  

Centrally located, ARL has an owned and operated, same-day pick-up and delivery to ARL courier service for our laboratory clients. This means our highly trained medical laboratory staff can provide accurate results in less time.  Results are available in real-time via Epic and EpicLink.

ARL is partnered with ARUP Laboratories when extremely specialized testing is required and with Associates in Pathology, SC for anatomical pathology testing.

Patients with valid laboratory orders both in and out-of-network may go to almost any of our convenient community locations for lab work. Both specimen collection and much of the testing are performed on-site, enabling us to provide results as soon as possible. 

ARL is dedicated to the field of Clinical Laboratory Science and proudly offers an intensive 9-month Clinical Laboratory Science Program for students affiliated with baccalaureate degree CLS programs.
