Information about the Medical Laboratory Technician License
Thank you for your interest in the California Medical Laboratory Technician (MLT) license.
Laboratory Field Services (LFS) requires applicants to submit documentation of academic coursework and clinical training or work experience to qualify for licensure.
Work experience in California as an unlicensed laboratory staff person will not be accepted as qualification toward any clinical laboratory license.
Please note that biotech/pharmaceutical, forensic, academic, veterinary, research, and student laboratory experience cannot count as work experience or training for any clinical license.
Scope of practice
- This license allows you to perform clinical laboratory tests or examinations classified as waived or of moderate complexity under CLIA, report the test results and perform phlebotomy.

All non-U.S. transcripts must be evaluated by the American Association of Collegiate Registrars and Admissions Officers (AACRAO). This allows LFS to determine if your education is equivalent to a U.S. college or university education. ACCRAO will send an evaluation of your educational institution and academic courses directly to LFS.
