Public Health Laboratory

The Public Health Laboratory is our community's first line of defense against public health threats like infectious diseases, toxins, and biohazards. Local health professionals, clinics, hospitals, and even law enforcement rely on the Public Health Laboratory to test and identify substances that could pose a serious risk to public health.

Under a joint powers agreement, Stanislaus County Public Health Laboratory services are provided by the San Joaquin County Public Health Lab in Stockton, CA.

To better serve your needs, there will be a daily courier service passing through Stanislaus County Public Health. Please use the appropriate San Joaquin County Public Health requisition, filling them out with complete information including collection time and date, test requested, and specimen background information.

NOTE: Certain types of specimens will continue to require Public Health approval before they can be submitted for testing at the Public Health Laboratory. If you have questions about testing for communicable diseases or outbreaks contact the Stanislaus County Public Health Communicable Disease program at (209) 558-5678.
