A Beginner's Guide to Blood Cells

• Includes a brand new chapter on emergency morphology, designed to make the clinical significance and urgency of certain laboratory findings clear for biomedical scientists and to assist trainee haematologists in the recognition of major clinically important abnormalities
• Contains exceptional full colour images throughout 
• Introduces important basic concepts of hematology, setting haematological findings in a clinical context
• Provides a fully updated self-assessment section
• An essential resource for trainee haematologists, biomedical scientists, and biomedical science and medical students
