Chemistry Division

The Clinical Chemistry Division provides chemistry laboratory services for both Harborview Medical Center, the University of Washington Medical Center and Northwest Hospital. Each Medical Center has a General Clinical Chemistry Section, providing around the clock testing for high volume analytes and those requiring rapid turn-around times. Other chemistry sections (Endocrinology, Special Chemistry, and Toxicology) are located at only one site, with specimens from all hospitals being analyzed in the same facility.
