The laboratory professionals at Overlake Medical Center work closely with the medical staff to provide excellent clinical and anatomic pathology services to both hospitalized patients and outpatients. The laboratory is committed to meeting the ever-changing healthcare needs of our community through continual education, process improvement and adoption of new technologies. Our role in community health and wellness is providing quality diagnostic services with efficiency and accuracy.
The laboratory provides comprehensive testing in the areas of chemistry, hematology, serology, microbiology and point of care. In addition to our onsite capabilities, we have established long-term associations with excellent secondary reference laboratories to provide esoteric testing in the areas of virology, toxicology, cytogenetics and molecular biology.
The Overlake laboratory is a member and part owner of PACLAB, a Network Laboratory that partners with nine other Puget Sound Hospitals. The PACLAB is recognized as being one of the most successful laboratory/hospital ventures in the United States. In addition to the inpatient laboratory, there are four laboratory outpatient service centers available for easy patient access. Please see the listing on this page.
Overlake contracts with Incyte Diagnostics for pathology services. The pathologists are board-certified in clinical and anatomic pathology (surgical pathology, cytopathology, fine needle aspiration biopsy and autopsy). The pathologists are available for consultation during regular business hours.
Main Hospital Laboratory
The hospital laboratory supports all inpatient departments for laboratory testing services including, outpatient surgery, inpatient surgery, heart room, emergency room, and all nursing units. After normal business hours when the outpatient service centers are closed, physicians may send patients with STAT or URGENT to the hospital laboratory for services. Please have patients check in at the admitting desk in the lobby to register prior to going to the laboratory.
