Program Description

The Department of Pathology and Laboratory Medicine at Children’s Hospital Los Angeles, in affiliation with the Keck School of Medicine of the University of Southern California, offers a two-year ComACC accredited Clinical Chemistry Fellowship. The program provides training in all areas of the field, ensuring the acquisition of skills, knowledge and experience required to successfully lead and direct a clinical chemistry laboratory. The fellowship offers comprehensive training in all fundamental laboratory aspects of diagnostic medicine, clinical consultation related to clinical chemistry, translational research, quality management, and laboratory management and administration.

Bench rotations, clinical rounds, didactic lectures, grand rounds, and conferences enhance the fellow’s training. Research opportunities specific to clinical and translational studies in all specialty areas are also available. Collaborative laboratory and clinical chemistry training is held at Children’s Hospital Los Angeles, Keck Hospital of the University of Southern California, The University of Southern California USC Norris Comprehensive Cancer Center, and Los Angeles General Medical Center giving fellows extensive and diverse experiences in both pediatric and adult patient populations.

The first year is heavily devoted to the fundamental laboratory aspects of clinical chemistry. Fellows are trained at the bench by clinical laboratory scientists, supervisors, section managers, and section directors in such a manner that they become proficient in each laboratory section. The first year is mostly spent on didactics and training in each laboratory section, with some time spent preparing presentations for laboratory rounds, case follow-ups, and consultations with clinicians. The remainder of the training entails research projects, laboratory medicine section rotations, and formal course and seminar attendance. The second year is more focused on research, clinical rotations, and on-call service.

The State of California requires individuals holding doctoral degrees to be licensed before they can be employed in a laboratory to perform diagnostic tests, i.e. assume a position directing a laboratory. This training schedule allows fellows to complete a year-long accredited program and become eligible for the State of California limited license in Clinical Chemistry.
