Haematology is composed of five parts. The first part acts as an introduction to the topic and looks at major haematology parameters and techniques as well as haemopoiesis and bone marrow. The second part looks at red blood cells, white blood cells, and anaemia. The third part covers haematological malignancies and introduces classification systems. The fourth part considers normal haemostasis and examines bleeding disorders, thrombophilia, acquired disorders of haemostasis, and anticoagulation. Finally, the text ends with different case studies in haematology.
