Veterinary Technician's Handbook of Laboratory Procedures is a quick-reference guide to conducting common laboratory tests. Carefully designed for fast access, the book covers common laboratory equipment, quality control, blood analysis, urinalysis, parasitology, and cytology. Important information is clearly and succinctly outlined for frequently used lab tests, providing step-by-step procedures, discussions of common errors, and tips and tricks, with more than 200 color images to aid in identification.
A companion website offers case studies, crossword puzzles, figures from the book in PowerPoint, and additional figures not found in the printed book at www.wiley.com/go/bellwoodhandbook. Veterinary Technician's Handbook of Laboratory Procedures is an invaluable tool for finding essential information on performing a wide range of laboratory tests.
