This core textbook provides a foundation in the molecular and cell biology that underpins haematology, allowing students to more easily understand the clinicopathological features of blood diseases, which are discussed in detail. The book covers all aspects of laboratory and clinical haematology, taking a practical approach by incorporating self-evaluation questions and learning objectives. These will give students not only the information needed to understand the topic but also clear indications of the core knowledge required to progress within the field of haematology.Building on the success of earlier editions authored by renowned haematologist Barbara J Bain, this textbook has been updated and expanded by seven experts in the field, with entirely new chapters on blood cancers and transfusion as well as new test cases and self-assessment questions. It is based on the curriculum of haematology teaching within Imperial College London, but it is equally suitable for medical students, trainee nurses, physician associate apprentices and biomedical science students from other institutions.
