Therapeutic drug monitoring and pharmacogenomics are both pharmacy-related areas within the clinical laboratory. Although each is considered a sub-discipline within laboratory medicine, the two fields overlap significantly. This course provides an overview of each of these laboratory sub-disciplines and discusses the utility, rationale, and practice of each one. The course is intended for clinical laboratory technologists and technicians and other health care personnel who are responsible for prescribing and administering therapeutic medications.
