Haematology is the study of the disorders of the cellular and coagulable components of the blood. This encompasses a number of important diseases, which include anaemias, leukaemias, and other disorders of the bone marrow and of blood coagulation and haemostasis. This subject is taught as part of a pathology course and relies upon a sound knowledge of both basic science and laboratory practice. This sixth edition of the Lecture Notes on Haematology seeks to integrate the physiological, pathological and clinical aspects of haematology at a level suitable for students and other allied health professionals. In light of the generally overcrowded medical curriculum, this book concentrates, therefore, on the subject's core knowledge. Advanced information, which students need not recall in examinations, is clearly marked and included only where necessary. Each chapter opens with a list of objectives that summarise information. Radically rewritten with new artwork, and more clinically relevant than previous volumes, this 6th edition includes brief sections on approaches to investigating haematological problems.
