This encyclopedia examines more than 125 of the most important and commonly performed medical tests, providing readers with information about how and why they are performed and how each test contributes to monitoring health and diagnosing and treating medical conditions. Whether it's to proactively monitor health, diagnose a condition, or assess how well a particular treatment is working, we all undergo a variety of medical tests throughout our lives. While these tests provide valuable information for doctors and patients, they can sometimes carry significant risks, provide ambiguous or incorrect results, or raise more questions than they answer. Contrary to what some may think, medical testing isn't a simple "yes or no" science carried out by computers in a lab—it is a dynamic process that relies heavily on human detective work and interpretation. Medical Tests in Context: Innovations and Insights highlights more than 125 tests performed across a wide range of medical specialties. Each entry in this encyclopedia follows a standardized format that provides readers with information about how, when, and why the test is conducted; the preparation and risks; how results are determined and where errors might occur; and its history. A collection of case studies offers real-world examples of the successes—and shortcomings—of medical testing.

Because of the current progress in molecular medicine (genomics, proteomics), a plethora of new and often human-specific targets are being identified. These targets often play a significant role in the pathogenesis of diseases, and identifying them offers the potential for early diagnosis and intervention. An early in vivo validation of specific ligands binding to these targets in humans is needed to as- sess their potential for targeted imaging and radiotherapy. Further- VI Preface more, such validation studies may allow for a better understanding of the molecular processes underlying phannacologic activity and therefore for a more successful development of phannaceuticals in general. The purpose of the Ernst Schering Research Foundation (ESRF) Workshop 48 was to provide a forum for an open exchange on the state of the art in the early development of such radiophanna- ceuticals. Experts from academia, industry, and regulatory authori- ties were invited to give presentations on aspects covering the identi- fication of targets, preclinical studies on the safety of ligands, as well as their validation in human clinical trials. It was our intention to cover both the opportunities and the challenges that scientists in this field are facing. Radiopharmaceuticals are uniquely suitable for the above-men- tioned target validation studies.
