Preface Purpose Pocket Guide to Diagnostic Tests is intended to serve as a pocket reference manual for medical and other health professional students, house officers, and practicing physicians. It is a quick reference guide to the selection and interpretation of commonly used diagnostic tests, including laboratory procedures in the clinical setting, laboratory tests (chemistry, hematology, and immunology), microbiology tests (bacte- riology, virology, and serology), diagnostic imaging tests (plain radi- ography, CT, MRI, and ultrasonography), and electrocardiography. This book will enable readers to understand commonly used diagnostic tests and diagnostic approaches to common disease states. Outstanding Features • Over 350 tests are presented in a concise, consistent, and readable format. • Fields covered include internal medicine, pediatrics, general surgery, neurology, and gynecology. • Costs and risks of various procedures and tests are emphasized. • Literature references are included for most diagnostic tests. • An index for quick reference is included on the back cover. Organization This pocket reference manual is not intended to include all diag- nostic tests or disease states. Rather, the authors have selected those tests and diseases that are most common and relevant to the general practice of medicine. The Guide is divided into eight sections: 1. Basic Principles of Diagnostic Test Use and Interpretation 2. Laboratory Procedures in the Clinical Setting 3. Common Laboratory Tests: Selection and Interpretation 4. Therapeutic Drug Monitoring: Principles and Test Interpretation 5. Microbiology: Test Selection 6. Diagnostic Imaging: Test Selection and Interpretation 7. Basic Electrocardiography 8. Diagnostic Testing: Algorithms, Nomograms, and Tables Intended Audience In this era of rapidly changing medical technology, many new diagnostic tests are being introduced every year and are replacing older tests as they are shown to be more sensitive, specific, or cost-effective.
