Laboratory Services


Clinical laboratory professionals are key members to today's health care team, and your quality medical care depends on them. Laboratory professionals have the skill to unlock important medical information that is pivotal to the diagnosis, treatment, and prevention of disease.

Every day nurses, physicians, and other medical workers rely on laboratory professionals to perform test on body fluids, interpret the results, and help provide a complete picture of a patient's health. Using modern biomedical equipment and complicated analysis, clinical laboratory scientists can detect the presence of cancer, identify infectious viruses and bacteria, and measure glucose, cholesterol, drug levels in blood, and a variety of other tests.

Laboratory professionals are by your side, working to diagnose, treat and prevent disease.

John C. Fremont Health Care District is proud of our laboratory staff and their competency. Our lab is surveyed every 2-years on the Clinical Laboratory Improvement Act (CLIA) by the State of California, Department of Public Health. Our lab has had ZERO deficiencies for the past 10 years.

Our laboratory offers a wide range of tests on-site, namely: Hematology, Urinalysis, Blood Gases, Chemistry, Coagulation, Microbiology, Serology and Blood Bank. For tests not performed in our lab, we have arrangements with a reference lab. We provide lab service for the community and industries in our area. We offer both pre-employment and routine drug screenings and participate in several health fairs during the year.
