Haematology is the study of the morphology and physiology of blood.  The haematology laboratory set in a healthcare setting is concerned with the diagnosis and monitoring of diseases of the blood and blood-forming organs. Biomedical scientists working in a haematology laboratory perform an array of blood tests that investigate the cellular elements blood and a number of proteins including haemoglobin and clotting factors. Haematological tests are performed on blood samples to diagnose diseases such as leukaemia, anaemia and abnormalities of blood coagulation. On any given day, working as a member of a team, a haematologist will be required to use their training to work in a variety of healthcare environments. These may include haematology, haemostasis or blood transfusion laboratories. Haematology is another rapidly developing discipline which deals
with many aspects of those diseases which affect the blood such as anaemia, leukemia, lymphoma, and clotting or bleeding disorders.Another important activity is the management of blood transfusion services. Many haematologists are involved, not only in the laboratory diagnosis and management of patients with blood diseases, but as clinical consultants. They also provide advice on the diagnosis and management of patients referred to them by medical colleagues, where the disease impacts on some aspect of the patient’s blood.
