Book excerpt: Diagnostic Cytology and Hematology of the Horse is a practical reference that presents common clinical findings in an easy-to-use text/atlas format. A general chapter discusses sample collections and techniques, followed by a 'systems' approach and chapters on specific types of fluid. Within systems chapters, normal findings are established and then abnormal findings are presented by class of problems, such as bacterial lesions, fungal lesions, parasitic lesions, etc. in the case of the eye. Algorithms on sample evaluations enhance text discussions by guiding readers to the most likely cytologic diagnosis.
