Equine Clinical Pathology is the first complete resource for hematology and clinical chemistry in horses. Encompassing the basic principles and advanced interpretation, the book's single-species approach to pathology allows for focused coverage of the unique disease characteristics of equids. Equine Clinical Pathology is equally useful for anyone using clinical pathology as a diagnostic tool, from beginning student to experienced specialist.
The heart of the book is organized by body system, making it easy to find and apply information. Chapters cover general laboratory medicine, including instruments and techniques, hematology, and proteins as well as specific organs, such as the kidney and liver. Equine Clinical Pathology is a useful bench-side reference for anyone involved in laboratory medicine for the horse.
Rezensionen / Stimmen
All photographs have excellent resolution and augment the text well. Overall, this book is a superb reference that provides readers with clear, concise, and clinically relevant information regarding equine clinical pathology. (Journal of the American Veterinary Medical Association, 15 September 2015) Overall, this book should be very useful to student and equine practitioners. (Doody s, 24 October 2014) The material provided in this book is well written and supported by adequate numbers of photomicrographs, diagrams, and charts. While the intended target audience is wide, this book appears to be particularly appropriate for senior veterinary students, clinical pathology residents, and equine practitioners. Clinical pathologists and equine specialists will find this text to be a helpful adjunct to their reference library. (Veterinary Clinical Pathology, 16 October 2014)
