Practical Veterinary Urinalysis

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.
