Author Information: Alec Saitman, PhD, DABCC (CC, TC) completed fellowship training in Clinical Chemistry and Toxicology in the Department of Pathology at the University of California, San Diego. Dr. Saitman is board certified by the American Board of Clinical Chemistry (ABCC) in Clinical Chemistry and Toxicological Chemistry. He is currently the Technical Director of the Core Laboratory at Providence Regional Laboratories in Portland, Oregon. His research focuses on the development of small molecule quantitation assays using mass spectrometry. He is particularly interested in establishing efficient production workflows in toxicology testing to meet the growing testing demands in his laboratory.
Reviewer Information: Kevin Foley, PhD, MT, DABCC is the director of Clinical Pathology for Kaiser Permanente Northwest. He has been in this position since 2009. After becoming a medical technologist, Kevin went on to earn a PhD in pharmacology. He then completed a fellowship in clinical chemistry. Kevin has also held full-time faculty positions at the University of Vermont, Northern Michigan University, and Mayo Clinic, Rochester.
