This book will, for the first time, provide a unique volume of all Biomedical Scientists need to know about Blood Science. It will assume basic knowledge to level 4 of the MSC and consequently offer a level 2/3 undergraduate, postgraduate, and specialist training text.   The chapters below illustrate the source of the main two topics.  Immunology and genetics (minor but necessary) will be inserted across chapters as appropriate.  (Immunology, previously a subspecialty of its own, now has no home and therefore will be presented in all three sub-types, blood science, infection science, cell science.)   Introduction to Blood Science and the role of the Pathology Laboratory Basic laboratory skills and methods in Blood Science role of the practitioner Red blood cells   physiology Red blood  cells -  pathology (anaemia etc) White blood cells   physiology White blood cells   pathology (mostly neoplasia) Haemostasis   physiology Haemostasis   pathology (thrombosis and haemorrhage) Blood Transfusion   Mechanisms and processes  - antibody/antigen reactions Blood Transfusion   Practice - group and save, cross match, reactions Immunology   physiology of the immune system and role of inflammation Immunology   pathology (hypersensitivity, allergy, transplantation) Biochemistry   the kidney, fluid and electrolytes and acid-base disorders (U Liver (LFTs) Biochemistry  -  Atherosclerosis and its risk factors Biochemistry   Bone: calcium, phosphates, PTH Biochemistry   Endocrinology (the pituitary, thyroid, diabetes, adrenal, reproductive) Biochemistry     Gastrointestinal and Nutritional Disorders Spare chapter  - puzzles and conundrums in interpretation of cross-discipline cases   Each chapter will have objectives, diagrams, figures, case studies, a summary/key point table and references. There will be liberal cross-referencing, with emphasis on the relationship between the two disciplines.
