What does RDW mean in UNCLASSIFIED
RDW stands for Red Distribution Width. It is a measure of variability in the size of red blood cells (RBCs) in a blood sample. RDW is expressed as a coefficient of variation (CV), which is a percentage that represents the standard deviation of the RBC distribution divided by the mean RBC size.
RDW meaning in Unclassified in Miscellaneous
RDW mostly used in an acronym Unclassified in Category Miscellaneous that means RBC Distribution Width
Shorthand: RDW,
Full Form: RBC Distribution Width
For more information of "RBC Distribution Width", see the section below.
What Does RDW Mean?
RDW measures the variation in RBC size, which can be caused by a variety of factors, including:
- Iron deficiency: Iron deficiency can lead to the production of smaller RBCs, resulting in a higher RDW.
- Vitamin B12 or folate deficiency: Vitamin B12 and folate are essential for the production of RBCs. Deficiencies in these vitamins can lead to the production of larger RBCs, resulting in a lower RDW.
- Thalassemia: Thalassemia is a genetic disorder that affects the production of hemoglobin. This can lead to the production of abnormal RBCs, resulting in a higher RDW.
- Sickle cell anemia: Sickle cell anemia is a genetic disorder that affects the shape of RBCs. This can lead to the production of crescent-shaped RBCs, resulting in a higher RDW.
RDW Reference Range
The normal reference range for RDW is typically between 11.5% and 14.5%. However, it is important to note that the reference range may vary slightly depending on the laboratory.
Essential Questions and Answers on RBC Distribution Width in "MISCELLANEOUS»UNFILED"
What is RDW?
RDW (Red Blood Cell Distribution Width) is a measure of the variation in size of red blood cells (RBCs) in the blood. RBCs are responsible for carrying oxygen throughout the body.
Why is RDW important?
RDW can be an indicator of underlying health conditions, such as anemia, iron deficiency, or certain blood disorders.
What is a normal RDW range?
Normal RDW ranges vary slightly among laboratories, but typically fall between 11.5% and 14.5%.
What causes an elevated RDW?
Elevated RDW can be caused by a variety of factors, including:
- Iron deficiency anemia
- Vitamin B12 deficiency
- Folate deficiency
- Liver disease
- Kidney disease
- Certain blood disorders, such as sickle cell anemia
What causes a decreased RDW?
Decreased RDW is less common and can be caused by conditions such as:
- Polycythemia vera (a condition where the bone marrow produces too many red blood cells)
- Spherocytosis (a condition where red blood cells are abnormally spherical in shape)
How is RDW measured?
RDW is typically measured as part of a complete blood count (CBC). A blood sample is drawn from a vein in the arm and analyzed using a machine that measures the size and shape of red blood cells.
What does an elevated RDW mean?
An elevated RDW may indicate the presence of an underlying health condition, such as anemia or liver disease. Further testing may be necessary to determine the specific cause.
What does a decreased RDW mean?
A decreased RDW is less common and may be associated with certain blood disorders or conditions that affect red blood cell production.
Final Words: RDW is a useful measure of the variability in the size of RBCs in a blood sample. RDW can provide valuable information about the underlying causes of anemia and other blood disorders. If your RDW is outside of the normal reference range, it is important to discuss this with your healthcare provider for further evaluation.
