What ails you? More often than not, the answer to whatever is making you sick begins with diagnostic testing in the laboratory.

Each year, more than 130,000 tests are performed by our skilled and highly educated pathologists, technologists, technicians and lab staff. We provide approximately 80 percent of the diagnostic testing relied upon by our providers to aid them in discovering, treating and monitoring various illnesses.

Our services include:

  • Regional pathology lab services
  • Clinical lab services:
    • Chemistry
    • Hematology
    • Microbiology
    • Urinalysis
    • Serology
    • Transfusion services


For inpatient services at the main laboratory located within the Hospital, we operate 24 hours a day, seven days a week, just like the Hospital. Outpatient hours are 7:30 a.m. to 6 p.m., Monday through Friday, and 8 a.m. to 2 p.m. on weekends.
