Laboratory Field Services (LFS)

Our Mission

The mission of the Laboratory Field Services branch (LFS) is to ensure quality standards in clinical and public health laboratories and laboratory scientists through licensing, examination, inspection, education, and proficiency testing.

LFS is the primary link between the health of California citizens and quality oriented, accurate and reliable clinical laboratory testing. LFS provides oversight for clinical and public health laboratory operations and for the licensed and certified scientists and other testing personnel who perform testing in clinical laboratories.

COVID-19 Information for Travelers Request documentation that COVID-19 testing required for travel was performed by a government-approved laboratory.     



New Certificate in PDF Format
Effective October 7, 2019, LFS will no longer mail license certificates. We will be introducing a new online licensing system for clinical and public health laboratories. For applications approved in our new system, we will email the license certificates in a PDF format which can be downloaded and printed as many times as you need.
Note: This does not apply to Tissue Bank, Cytology, and Biologics (Blood) Bank programs.
