Clinical Laboratory Science
Since 1977, the San Francisco State University Clinical Laboratory Science (CLS) program has been a cornerstone in preparing post-baccalaureate candidates for rewarding careers in medical laboratories, clinics and biomedical research environments. As one of the most unique in-person training programs in California, we offer students unparalleled opportunities to gain hands-on experience in real clinical laboratory settings. This practical exposure, combined with our comprehensive curriculum, equips our graduates with the skills and knowledge necessary to excel in their chosen career paths within the dynamic field of clinical laboratory science.

About the Clinical Lab Science Program
Overview
The program offers expert guidance, both on campus and at affiliated clinical sites. The first semester on campus includes five courses specifically designed for CLS training. The remaining 40 weeks are spent at affiliated clinical sites, completing an internship. Once finished, interns are eligible to challenge the California State and National examinations for required licensure. A new class of CLS interns starts on campus every fall and spring session.
Visit the Clinical Laboratory Science Program website for more information.
Clinical Laboratory Scientist Career
The job responsibilities of a Clinical Lab Scientist involve the collection and analysis of body fluids, tissues and cells in order to diagnose diseases and monitor the progress of treatments. Advances in molecular diagnostics and cryopreservation are welcoming new surroundings for licensed CLS. The US Bureau of Labor Statistics projects 11% growth for clinical laboratory technologists and technicians from 2018 to 2028, much faster than average.
Licensure and Certification
Please read the Cal State Notice to Students RE: Professional Licensure and Certification.
Candidate Requirements
The CLS Program seeks candidates with post-baccalaureate degrees in biological science majors, including but not limited to Biology, Chemistry, health profession-related degrees, Microbiology or equivalent fields. Prospective applicants should have a minimum GPA of 3.0 and must have completed additional coursework in Immunology, Medical Microbiology, Hematology, Biochemistry and Quantitative Analysis, as well as 3 semester units of Physics and college-level mathematics. It is crucial to note that core prerequisites in Hematology, Immunology and Medical Microbiology must have been completed within five years of the application deadline. Any coursework in these specific subjects completed more than five years before the deadline will not be considered as fulfilling the admission requirements. This time-sensitive requirement ensures that incoming students possess up-to-date knowledge in these rapidly evolving fields, setting the stage for a successful and enriching experience in our program.
