Red blood cell distribution width Red blood cell distribution width (RDW or RDW-CV or RCDW and RDW-SD) is a measure of the range OF variation of red blood cell (RBC) volume that is reported as part of a standard complete blood count. Usually red blood cells are a standard size of about 6-8 μm in diameter. A low RDW (below 10.2%) means that the red blood cells vary very little in size.

What does RDW mean in a blood test? If your doctor tells you that your blood work shows a high rdw-cv,  it simply means you have a higher than normal red blood cell  distribution. This may be caused by an iron … or B12 deficiency and  is usually easily treated with a change in diet and the addition of  supplements.f the RDW level is increased and the MCV level is normal. This can be caused by the beginning stages of a decrease in vitamin B12 or folic acid (a type of vitamin) in the body.

How can you differentiate between iron-deficiency anemia and thalassemia? The red cell distribution width (RDW) is high in iron deficiency anemia because there is a wide variation in red cell size. In mild thalassemia (alpha or beta), the red cells are strangely all the same size; there is virtually no variation. So the RDW is low.

- The RDW blood test can calculate the sizes of red blood cell count in a sample of blood, and normally an RDW test is performed as a part of a CBC test, which means complete blood count. The RDW blood test is dependent on the draw of another test, which is MCV, the mean corpuscle value.MCV and RDW are closely related when it comes to anemia and many other hematology disorders. The values influence each other.f your primary care provider diagnoses you with iron deficiency or anemia, your RDW blood test showed a low count. These levels, along with other combinations of blood counts, allow your physician to determine what kind of anemia is affecting you, and why it has presented symptoms.

Uses of the Red Cell Distribution Width Test in Medical Science To determine the exact cause of an elevated RDW, it is often necessary to also look at the MCV, which is another component of the CBC. MCV is the abbreviation for mean corpuscular volume and it measures the mean red blood cell volume, or the average size of the red blood cells in the sample.

RDW Blood Test Results Explained The RDW is elevated in these conditions. • RDW is useful in differentiating thalassaemia from iron deficiency anaemia. In thalassaemia, the RDW is normal while in iron deficiency anaemia the RDW is elevated. However, additional tests may be required to confirm the diagnosis. • In conditions such as vitamin B12 deficiency and folate deficiency, the size of the red blood cells can increase. This is called macrocytosis.

Red blood cell distribution width Human red blood cells. Red blood cell distribution width (RDW-CV or RCDW and RDW-SD) is a measure of the range of variation of red blood cell (RBC) volume that is reported as part of a standard complete blood count. Usually red blood cells are a standard size of about 6-8 μm in diameter.Certain disorders, however, cause a significant variation in cell size. Higher RDW values indicate greater variation in size. Normal reference range of RDW-CV in human red blood cells is 11.5-14.5%.If anemia is observed, RDW test results are often used together with mean corpuscular volume (MCV) results to determine the possible causes of the anemia.uman red blood cells.
