Walk-in lab testing

CMH strives to make the lab experience as easy as possible. You don't need an appointment for lab work. For your convenience, CMH offers walk-in labs during business hours. Lab work is also available after hours via the Emergency Department.

If a CMH provider has referred you to the lab, you don't need to bring any paperwork with you. It will already be in our system. If your physician isn't associated with CMH, please bring your lab orders. You can also ask your provider to fax them to 503.338.7589.
