Therapeutic Drug Monitoring: Newer Drugs and Biomarkers features timely topics such as the monitoring of classical and newer drugs, pharmacogenomics and the application of biomarkers in therapeutic drug monitoring. This reference also discusses the limitations of current commercially available immunoassays for therapeutic monitoring. It presents new and sophisticated techniques used for proper determination of blood levels and the clinical utility of therapeutic drug monitoring of contemporary drugs. Written by leading international experts and geared toward clinical pathologists, toxicologists, clinical chemists, laboratory professionals and physicians, this book is an essential resource on the current practice of therapeutic drug monitoring in improving patient safety.
