Clinical Laboratory Improvement Amendments (CLIA) Section

This process involves compliance with the federal Clinical Laboratory Improvement Amendments (CLIA) of 1988, which requires that all laboratories testing human specimens be certified by the federal government. The Los Angeles LFS Office manages the CLIA program.

The mission of the Clinical Laboratory Improvement Amendments (CLIA) section of Laboratory Field Services is to ensure compliance with State and federal clinical laboratory laws and regulations by performing biannual onsite inspections to ensure accuracy and reliability of laboratory test results and conducting review of laboratory performed proficiency testing results.

The CLIA program performs routine inspections of over 800 laboratories and validations of 36 accredited facilities each year. The program is also responsible for inspection of over 200 laboratories with a CLIA certificate of waiver annually.

To contact the Los Angeles LFS Office please call (213) 620-6160.
