Laboratory

Virginia Mason's laboratories provide superior customer service focused on meeting the needs of our patients and providers. Our team is committed to providing prompt, personalized service for your laboratory testing needs.

Locations:
We offer laboratory locations throughout Western Washington though our medical centers and Hospital & Seattle Medical Center. Follow the links below for more information about those locations.

Fasting:
To prepare for your visit to the lab some providers may ask you to fast for a test. Fasting requires no food or drink consumption except for water for 12 hours before the blood test. Medication generally does not affect fasting tests. If you have concerns about a medication you are taking interfering with a test please contact your provider. If you would like to know if your blood tests require fasting, you can check with your provider before coming in.

Day of laboratory visit:
All Virginia Mason medical centers and the Hospital & Seattle Medical Center laboratory offer walk-in service as we do not schedule appointments. When you visit us, you can proceed directly to the laboratory. For laboratory testing it is not necessary to check in at the front desk in the lobby, but you may need to if you are having other services performed during your visit. When planning your visit to the lab, please be advised our busiest hours are from 7 a.m. to 1 p.m., Monday through Friday. There is also a small laboratory in the Lindeman Pavilion, Level 8. The hours are 8 a.m. to 5 p.m., Monday through Friday.
