This invaluable Handbook provides a compendium of investigation relevant to modern medical practice. The first part of the book is patient-centered, describing key symptoms and signs along with tests which may be useful in reaching a diagnosis. The second part of the book is specialty-centered, and provides a comprehensive review of all available tests within a given subject. It provides a synopsis of most of the investigative techniques used in the basic medical sciences and the major clinical specialties. In addition there are sections devoted to imaging tests (radiology and nuclear medicine).
