Laboratory Services

For the convenience of our patients, Mid-Columbia Medical Center offers outpatient laboratory services at our main hospital as well as at two affiliated locations.

No appointment is required at any of our locations. Please check with your provider to ensure that lab work has been ordered and proceed to one of our locations for collection. If you have any questions, please contact one of our labs and they will be happy to assist you.

We encourage outpatients to utilize either Lab Express or Water’s Edge for outpatient lab work convenience.
