This thoroughly updated Seventh Edition of Interpretation of Diagnostic Tests is a must for residents and practitioners in every specialty. Arranged by organ system, the book summarizes the available tests for most diseases, explains what the results would mean, and discusses differential diagnoses. This edition features major revisions in cardiovascular, gastrointestinal, hepatobiliary, metabolic and hereditary, and genitourinary chapters, plus highlighted “Key Diagnostic Finding” information to aid accessibility. Readers can search for information in the way that best suits their needs–by index, table of contents, test results, or specific disease. Also included are extensive tables of normal and panic values, tables comparing test results in similar diseases, and an appendix of conversion factors between conventional and SI units.
