A hematology atlas is a medical reference book that contains detailed photographs of different types of blood cells, both healthy and diseased. It helps doctors identify blood-related health problems and can cover cancer cells and cells in animals. It can also be used as an educational text for medical students.
Hematology is the name for the area of medicine that focuses on the blood, diseases affecting the blood, and closely related organs and tissues, such as the bone marrow and spleen. A hematology atlas is a medical reference work that contains detailed photographs of different types of blood cells. It shows both what cells look like in their healthy state and what they look like when they are afflicted with various ailments and diseases. Its purpose is to help doctors and other medical personnel analyze blood cells and identify the cause of blood-related health problems. A hematology atlas is usually a physical book, although today it can also take the form of an archive stored on a computer or optical disc, such as a DVD.
A hematology atlas covers different cell types, such as red blood cells, various types of white blood cells such as neutrophils and lymphocytes, and platelets. It includes both images of these cells as they normally appear and as they appear when affected by pathogens in the bloodstream or by disorders that interfere with their normal production and development, such as sickle cell anemia and thalassemia. The atlases also contain images of other cells closely related to the blood flow, such as cells in the bone marrow and lymph nodes. Foreign microorganisms that infect the blood can also be shown.
Another type of cell covered by a hematology atlas are cancer cells, such as the malignant cells that cause lymphoma and leukemia. Closely related are abnormal blood cells that are not themselves cancerous but often appear in the presence of cancers affecting the blood, such as damaged white blood cells that appear in large numbers in people with leukemia. This information is important in diagnosing these diseases.
In addition to the general references, there are also hematology atlases with a more specific emphasis. For example, some atlases focus on identifying different types of cancer cells. Atlases intended for veterinary medicine or animal research show blood cells from various animal species rather than human ones and can be general works covering a large number of common animals or specialized texts focusing on specific types of animals, such as rodents or birds. In some cases, a hematology atlas may include additional explanatory text that introduces important concepts and terms in hematology so that the atlas can be used as an educational text for medical students.
