Haematology is the study of blood and blood marrow disorders. Haematologists can diagnose anaemia, infection, haemophilia, blood-clotting disorders, and cancers such as leukaemia, lymphomas and myeloma requiring chemotherapy. A haematologist works closely with GPs and can perform bone marrow biopsies and interpret diagnoses. Haematologists are also advising in blood transfusion and organ transplant medicine.
The haematopathologist also focuses on diagnostic work for hematopoietic and lymphocyte-rich tissues including the lymph nodes, the spleen, thymus, and other lymphoid tissue. This is usually done in the lab. The tests used are: complete blood count, platelet count, haematocrit, haemoglobin concentration, differential white blood count, red blood cell indices, prothrombin time (clotting test).
