Practical Veterinary Urinalysis

by Carolyn A. Sink, Nicole M. Weinstein

Overview

Practical Veterinary Urinalysis is a comprehensive, clinically relevant resource for the veterinary laboratory. This bench-top guide covers sample handling guidelines, interpretation of dry chemical analysis, and recommendations for physical and microscopic evaluation. Emphasizing diagnostic techniques and result interpretation, Practical Veterinary Urinalysis is an ideal aid for anyone who performs and interprets urinalysis testing.

Beginning with an overview of renal physiology and urine production, the main focus of the book is examination and analysis of urine samples, including physical properties, chemical analysis, and sediment examination. Additional chapters review diagnostic tests and considerations for proteinuria, advanced diagnostics, quality assurance and laboratory set-up. Practical Veterinary Urinalysis is an invaluable tool for achieving accurate and reliable laboratory results and is a useful addition to any veterinary library.

Editorial Reviews

Overall, this book is reasonably priced and will be a useful and relevant addition to any laboratory or veterinary medical library, with valuable information for both veterinarians and veterinary technicians.”  (Journal of The American Veterinary Medical Association, 16 September 2012)

“A 'must' for any vet's reference and for veterinary students.”  (Midwest Book Review, 1 July 2012)

“This book would be a great addition to any practice to encourage the use of urinalysis.”  (Veterinary Record, 28 July 2012)

From the Publisher

Reviewer: Melissa C Skowronski Dodd, DVM, MS (University of Illinois College of Veterinary Medicine)
Description: This is an excellent guide to not only performing high-quality veterinary urinalysis but to understanding the underlying physiology and pathology that contributes to the results.
Purpose: The goal is to provide veterinary students, clinicians, and laboratory professionals with the tools and knowledge to perform and interpret urinalysis.
Audience: This book is appropriately written for this audience.
Features: It covers all aspects of urinalysis, including renal physiology, specimen handling and storage, chemical and microscopic urinalysis, proteinuria, advanced diagnostic testing of urine, and laboratory quality control. The color photos of microscopic findings in urine are especially helpful for interpreting sediment findings. The book is spiral-bound to allow the pictures to be easily referenced during microscopic evaluation. The tables throughout the book provide a quick reference for clinicians looking for differentials for abnormal urine dipstick results, but additional information is available in the chapters if more in-depth study is desired. The chapter on renal physiology is a quick and simplified discussion, and includes additional references if more information is needed. The book uses color pictures and discussions of the different tools available for urine collection, analysis, and storage. It follows the process from why urine is analyzed, how to collect it, the benefits and disadvantages of each product designed to analyze it, how the urine results relate to the patient, and what other tests are available to confirm suspected disease or track disease progression.
Assessment: The analysis that is performed on urine can be difficult to interpret and important abnormalities may be overlooked early in the course of disease. This book would help any clinician in any veterinary hospital with urinalysis interpretation.
