Quest Diagnostics now operates the majority of former PeaceHealth Laboratories facilities. While PeaceHealth no longer provides general outpatient laboratory testing services, testing remains available at specific critical access hospitals.

These exceptions include Cottage Grove Community Medical Center (OR), Peace Harbor Medical Center (OR), Peace Island Medical Center (WA), and United General Medical Center (WA). PeaceHealth facilities remain connected to various regional medical centers, including those in Ketchikan, Cottage Grove, and Sacred Heart areas. For local testing services, customers can find nearby Quest locations.
