Opis

Designed to be a practical guide for the veterinary practitioner and technician who incorporate haematology studies in the office setting, this work provides step-by-step guidelines for the collection and processing of blood samples and interpretation of the haemogram. It also serves as a guide to patient assessment and treatment planning for all common haematological disorders and diseases in dogs and cats. Colour is used throughout the book. Clinical case studies and related self-assessment questions are included with cross references to related portions in the text. The guide is designed to work with all currently available blood analyzer systems, providing detailed guidelines for interpretation of the haemogram, identification of artifacts and false positive results.
