This book discusses the importance of a careful history, detailed clinical examination and the judicious use of laboratory and imaging investigations in the elucidation of the correct diagnosis. It is helpful for the clinician to serve the medical profession.

First published in 1912, French's Index of Differential Diagnosis helps clinicians in the differential diagnosis of any condition which may be seen in hospital or general practice. Arranged alphabetically by symptom, the text helps readers identify each presentation, describes the different diagnoses that it could represent, and explains the tests used to make a diagnosis. Colour clinical photographs help with diagnoses at a glance. The book is completely revised - many sections are largely rewritten, new ones added, diagnostic methods updated, many old illustrations replaced and others inserted. The emphasis, however, remains the same: the importance of a careful history, detailed clinical examination and the judicious use of laboratory and imaging investigations in the elucidation of the correct diagnosis. This reference is indispensable to medical students as well as trainee and established doctors in both general and hospital practice.
