Amitava Dasgupta received his Ph. D in chemistry from Stanford University and completed his fellowship training in Clinical Chemistry from the Department of Laboratory Medicine at the University of Washington School of Medicine at Seattle. He is board certified in both Toxicology and Clinical Chemistry by the American Board of Clinical Chemistry. Currently, he is a tenured Full Professor of Pathology and Laboratory Medicine at the University of Kansas Medical Center and Director of Clinical Laboratories at the University of Kansas Hospital. Prior to this appointment he was a tenured Professor of Pathology and Laboratory Medicine at the University of Texas McGovern medical School from February 1998 to April 2022. He has 252 papers to his credit. He is in the editorial board of four journals including Therapeutic Drug Monitoring, Clinica Chimica Acta, Archives of Pathology and Laboratory Medicine, and Journal of Clinical Laboratory Analysis.Jorge Sepulveda received his M.D. from the University of Lisbon, Portugal, and his residency training in Laboratory Medicine and Ph.D. degree in Cell and Molecular Biology from Baylor College of Medicine, Houston, Texas. He is board certified by the American Board of Pathology in Clinical Pathology and Transfusion Medicine. He has published over 35 research articles, review papers and book chapters, and serves as Associate Editor for the Archives of Pathology and Laboratory Medicine. Dr. Sepulveda has broad experience in laboratory medicine as medical director of various clinical laboratories, including at the Houston and Philadelphia Veterans Affairs Medical Centers and at the University of Pittsburgh Presbyterian and Shadyside Hospitals, and currently serves as Associate Medical Director of the Clinical Laboratories at the Columbia University Medical Center Campus of New York-Presbyterian Hospital.

Praise for the first edition:"This would be a must for the laboratory medicine resident who has to explain why results don't correlate with clinical disease." --Doody.com, 2013"It will be of great value to all laboratory directors and trainees in laboratory medicine and the technical staff who perform the tests in daily practice." --Donald Young, MD, PhD, Department of Pathology & Laboratory Medicine, University of Pennsylvania Perelman School of Medicine, Philadelphia, PA
