It is the science field that researches the structures,
duties and diseases of the blood cells and the organs such as bone marrow
producing blood cells.
Cells in the blood are classified in 3 groups: red blood
cells (erythrocytes), white blood cells (leucocytes) and blood platelet
(thrombocytes). From these cells, the red blood cells are responsible for the
carrying oxygen from lungs to tissues; leucocytes are responsible for the
protection of the body from microbes; thrombocytes are responsible for
providing the blood coagulation. Anemia, leukemia and bleeding disorders may
occur in relation to these cells. Before the birth, blood cells are produced by
the spleen and liver; after the birth, by stem cells at the middle part of the
bones. Adenoids and spleen also work with white blood cells to protect the body
from microbes. Besides, Hematology Department deals with the diseases related
to bone marrow or adenoids.
These disease groups can be summarized as below:
Cancerization of the cells in bone marrow or adenoids (leukemia’s,
Disruption of the blood cell productions in bone marrow
(anemia types, decrease of leucocyte and thrombocyte values)
Increase of the blood cell lysis
Disruption of the blood clotting (hemophilia’s)
Clotting of the blood in vascular system
What Are the Symptoms of Blood Diseases?
Decrease of Effort Capacity
Yellowing in Sclera
Need of Eating Abnormal Foods (soil, clay, sand etc.)
Bleedings that take a long time
Bruises at the body wihout any hit or trauma
If there are painless swellings (gland) in the neck,
underarms or groin; it is necessary to be examined by a hematologist. With a
simple blood test, the abnormality at your blood table can be easily figured out.
Which Methods Are Used in the Diagnosis of Blood Diseases?
Peripheral Smear (blood is examined under the microscope)
Examination of the Bone Marrow (Bone Marrow Aspiration and Biopsy)
Cell Lysis Tests
Examination of the Lymph Node Biopsy
