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.



Suspension of Annual Renewal Fee for Moderate/High Complexity Laboratories

On September 28, 2017, Governor Brown signed Assembly Bill 658 into law. This bill temporarily suspends the annual renewal fee for clinical laboratory licenses from January 1, 2018, until January 1, 2020. As of January 1, 2018, the annual renewal fee for clinical laboratory licenses will be suspended for two years. This means that if your laboratory renews its laboratory license on or after January 1, 2018, you do not need to pay a renewal fee. You still need to submit your renewal application which LFS will process. You will be issued a renewed license for 2019 as usual. Please note that this fee suspension does NOT apply to clinical laboratory registration renewals, or to new clinical laboratory license or registration applications.
