This comprehensive text examines normal hematopoiesis through diseases of erythroid, myeloid, lymphoid and megakaryocytic origins. Hemostasis and coagulation theory, testing, and instrumentation are also thoroughly discussed. Beautiful full-color illustrations throughout the text enhance comprehension and allow students to realistically visualize hematology concepts. Detailed, full-color illustrations appear near hematology concept discussions to visually support comprehension and recognition. Opening Case Studies present real-life scenarios to apply concepts presented in each chapter. Learning Objectives and Review Questions work together to list expected outcomes and then test those concepts for each chapter. A Bulleted Summary highlights the key concepts at the end of each chapter. Hematology/Hemostasis Reference Ranges inside the front and back covers provide quick reference. Three new chapters detail significant information: An Overview of Clinical Laboratory Hematology, Hematology in Selected Populations, and Monitoring Anticoagulant Therapy. All chapters have been revised to feature the most current technology and research updates. The included Glossary of Terms and consistent pedagogy ensure a cohesive, effective tool for learning. Two well-respected editors contributed more significantly to this third edition: George Fritsma shared his expertise for the Hemostasis section and Kathy Doig managed the pedagogical features.
