RDW-CV analysis
The blood is composed of water and dissolved substances as well as cells. The blood cells are divided into three groups: white blood cells, Is a part of the body’s immunity. It fights bacteria and foreign bodies that enter the body, red blood cells that transport oxygen from the lung to the rest of the body’s tissues, and the third group are the platelets that play a role in blood clotting
The RDW analysis is performed in several cases and is part of routine tests. These include:
- In cases of assessment of anemia or increase in the number of red blood cells and hemoglobin.
- When there is a suspicion of inflammation or infection, there is an increase in white blood cells.
- May be accompanied by some other analysis to measure the performance of blood clotting, or to know the number of platelets and the discovery of deficiency or increase them.
- When evaluating a suspected lack of immunity resulting from a lack of white blood cells.
- When performing leukemia diagnosis such as lymphoma and leukemia.
The RDW analysis is not serious and does not require any particular preparations; it is a routine examination. Among the diseases related to this test are: anemia, an increase in the polycythemia, an increase in leukocytosis or a decrease in the number of pellets (Leukopenia), or there may be a lack of platelets (Thrombocytopenia), or perhaps an increase in platelets (Thrombocytosis).
The RDW analysis includes several compounds, namely red blood cells, the most important compound in the blood, and hemoglobin compounds, and healthy levels are as follows in men (38.8-46.4%) and in women (35.4-44.4%); when low indicates anemia, When it rises, it refers to the increase in red blood cells, in addition to the hematocrit, where this value is often proportional to hemoglobin; it reflects the level of red blood cells from the total blood volume, – 93.3fL). When the hemoglobin level decreases, there is an indication of the cause Poverty blood.
