What makes you sick? At Grande Ronde Hospital, we want to know as much as you do. It’s part of our mission to help you feel better fast.

That's why the answer to what ails you usually begins with diagnostic testing at our Clinical 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 physicians to aid them in discovering, treating and monitoring various illnesses.  
Our services include:

  • Chemistry
  • Hematology
  • Microbiology
  • Urinalysis
  • Serology
  • Anatomic Pathology
  • Blood Banking

Our services are offered through two laboratory sites. The core laboratory is located within the hospital. For inpatient services, we operate 24 hours a day, seven days a week, just like the hospital. Our outpatient hours are 7:30 a.m. to 6 p.m., Monday through Friday, and 8 a.m. to 2 p.m. on weekends.

Our satellite laboratory is located at the Regional Medical Clinic. The satellite lab is open during clinic hours, which are 7 a.m. to 6 p.m., Monday through Friday.
