Contact Information & Locations

Northwest Clinical Laboratory takes pride in knowing we are large enough to meet the needs of our community while small enough to still maintain a personal touch in working with our customers and patients.

Our staff listens to the needs of our clients and customers and when feasible, adjusts our testing and/or procedures to better serve them. Our commitment is to provide quality, innovative laboratory services to our health care community.

Northwest Clinical Laboratory is located on the second floor of the main hospital building on the Northwest Hospital & Medical Center campus at 1550 N. 115th Street in North Seattle. Please stop at the patient registration desk to check in for your appointment.
