Hematology
Hematology is the branch of medicine concerned with the study of the cause, prognosis, treatment, and prevention of diseases related to blood. It involves treating diseases that affect the production of blood and its components. These components include blood cells, hemoglobin, blood proteins, bone marrow, platelets, blood vessels, spleen, and the mechanism of coagulation. Such diseases might include hemophilia, sickle cell anemia, blood clots known as thrombus, other bleeding disorders, and blood cancers such as leukemia, multiple myeloma, and lymphoma. The laboratory analysis of blood is frequently performed by a medical technologist or medical laboratory scientist.
Physicians specialized in hematology are known as hematologists or haematologists. Their routine work mainly includes the care and treatment of patients with hematological diseases. Some may also work at the hematology laboratory viewing blood films and bone marrow slides under the microscope. They interpret various hematological test results and blood clotting test results. In some institutions, hematologists also manage the hematology laboratory. Physicians who work in hematology laboratories, and most commonly manage them, are pathologists specialized in the diagnosis of hematological diseases. These specialists are referred to as hematopathologists or haematopathologists. Hematologists and hematopathologists generally work in conjunction to formulate a diagnosis and deliver the most appropriate therapy if needed. Hematology is a distinct subspecialty of internal medicine, separate from but overlapping with the subspecialty of medical oncology.
Hematologists may specialize further or have special interests in treating bleeding disorders such as hemophilia and idiopathic thrombocytopenic purpura. The latter condition is continuously studied by hematologists due to its unknown cause. They treat hematological malignancies such as lymphoma and leukemia which are cancers affecting the blood. Another focus area involves treating hemoglobinopathies including alpha-thalassemias and beta-thalassemias known as thalassemia syndromes. This category also includes abnormal hemoglobins like hemoglobin S, hemoglobin C, and hemoglobin E. The science of blood transfusion and the work of a blood bank falls under transfusion medicine. Bone marrow and stem cell transplantation is another key area especially with the use of technologies to extract and isolate hematopoietic progenitor cells.
Starting hematologists in the US complete a four-year medical degree followed by three or four more years in residency or internship programs. After completion they further expand their knowledge by spending two or three more years learning how to experiment diagnose and treat blood disorders. Some exposure to hematopathology is typically included in their fellowship training. Job openings for hematologists require training in a recognized fellowship program to learn to diagnose and treat numerous blood-related benign conditions and blood cancers. Hematologists typically work across specialties to care for patients with complex illnesses such as sickle cell disease who require complex multidisciplinary care. They provide consultation on cases of disseminated intravascular coagulation thrombosis and other conditions that can occur in hospitalized patients.
The laboratory analysis of blood is frequently performed by a medical technologist or medical laboratory scientist. These professionals view blood films and bone marrow slides under the microscope. They interpret various hematological test results and blood clotting test results. The process involves examining the physical properties of blood samples to identify abnormalities. This examination helps determine the presence of diseases like leukemia or anemia. Technologists analyze the structure and function of blood cells to support clinical decisions made by physicians. Their findings guide the treatment plans developed by hematologists and hematopathologists working together.
