Laboratory Services

The Sonoma Valley Hospital Laboratory is integral to the care of our patients and our community. We provide a full range of diagnostic testing including STAT testing, which your physician requests be completed within one hour of the blood draw. We have skilled phlebotomists on staff to draw blood samples in all our patient care settings.
