Stephen E. Kahn, Ph.D., DABCC, FAACC, is Professor (tenured) and Vice Chair of Clinical Services in Pathology and Laboratory Medicine at the Loyola University Health System (LUHS) - A Member of Trinity Health in Maywood, IL, USA. He is a faculty member in the Stritch School of Medicine and the Parkinson School of Public Health and Health Sciences. He has been a Loyola University of Chicago (LUC) employee since 1978 completing a two-year postdoctoral fellowship in clinical chemistry at the Loyola University Medical Center (LUMC) before becoming a Pathology faculty member in 1980. He earned his Ph.D. in 1979 in Biological Chemistry (researching mechanisms of mineralization) at the University of Illinois Medical Center in Chicago, IL. He is board-certified by the American Board of Clinical Chemistry and is a fellow of AACC’s Academy. Dr. Kahn's clinical and scientific interests include evidence based laboratory medicine, quality management systems, quality improvement, biomarkers of cardiac disease and cardiovascular risk, laboratory stewardship and utilization, toxicology and near patient (or point of care) testing. At LUHS, he presently serves as Associate Director of Clinical Laboratories, Division Chief for Clinical Pathology and Quality Medical Director for Pathology and Laboratory Medicine as well as Director of Core Laboratory Operations, Point of Care, Referred Testing and Toxicology. He has served on numerous groups in Loyola University of Chicago's Health Sciences Division (HSD), Stritch School of Medicine (SSOM) and Department of Pathology and Laboratory Medicine. He was a member of the HSD/SSOM Committee on Academic Rank and Tenure for 16 years chairing CART from 2008 – 2014. In the Trinity Health System, he is a member of the Laboratory Services Council, Laboratory Test Stewardship Group and has chaired multiple sub-groups in TH's Transforming Operations initiative. He is actively engaged in the clinical quality programs of the LUHS. Active throughout his career, Dr. Kahn is a Past-President of the American Association for Clinical Chemistry and AACC’s Academy. He presently is a member of AACC's Awards Committee. He has served on groups under the auspices of the American Medical Association, American Society for Clinical Pathology, Agency for Healthcare Research and Quality, Association for Clinical Laboratory Science, Clinical Laboratory Standards Institute, College of American Pathologists, the Centers for Disease Control's Laboratory Medicine Best Practices program, the Joint Commission and the National Institutes of Health. In 2011, he chaired the joint AACC/NACB Evidence-Based Laboratory Medicine Committee and the Arnold O. Beckman Conference on ‘Glycemic Control in the Hospital: Evidence, Issues and Future Directions.’ He is a recipient of AACC’s Lifetime Achievement Award, AACC’s Award for Outstanding Contributions in Service to the Field of Clinical Chemistry, three AACC presidential citations and several other awards. Dr. Kahn has devoted his life to service contributions at all levels and his career to education. He continues to teach a broad spectrum of trainees at the undergraduate and postgraduate levels. He has been invited to give more than 100 invited presentations in local, national and international venues. He has published over 75 peer-reviewed articles and chapters as well as nearly 100 abstracts and conference proceedings. His translational research interests include studies focusing on utility of lab testing for markers of tissue injury (particularly cardiac disease biomarkers and cardiovascular risk assessment), clinical toxicology, laboratory utilization, quality management systems and near patient testing. His interest in standardization led to his previously chairing an international subcommittee addressing harmonization of cTnI measurements and in helping to develop a framework leading to an international standardization program initiative (ICHCLR at www.harmonization.net)

I pursued training and certification in clinical chemistry because I really liked biochemistry and was interested in working in healthcare, preferably in a hospital setting. That led to my career in laboratory medicine and pathology.
Numerous sources identify that a large majority of objective patient data in the electronic medical record comes from the clinical laboratory or anatomic pathology divisions. While the value of the laboratory has always been critical to patient care, laboratory testing has never been more important, more visible and more needed than during the coronavirus pandemic.
