Red blood cell distribution width Usually red blood cells are a standard size. Certain disorders, however, cause a significant variation in cell size. Higher RDW values indicate greater variation in size. Normal range in human red blood cells is 11 - 15%.If anemia is observed, RDW test results are often used together with MCV results to figure out what the cause of the anemia might be. It is mainly used to differentiate between iron deficiency anemia, in which RDW is elevated, and other microcytic anemias.ormal range in human red blood cells is 11 - 15%.

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.ormal 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.

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.

RDW Blood Test Results Explained At the other hand, the red-cell distribution width coefficient of variation is expressed as a percentage and is calculated from the standard deviation and the mean corpuscular volume. In other words, the RDW (CV) is dependent upon the size of the red blood cells. Normal values lies between 11.6 – 14.6%.

What is RDW in CBC Blood Test? RDW is an early marker of several types of anemia, that’s because RDW value means how red cells sizes are distributed in the blood sample, the normal RDW value means that RBCs are in normal size or the same size, high or low RDW value means that the RBCs show variant sizes, in many types of anemia, RBCs appear in abnormal sizes which s detected by RDW value.

What is the significance of low RDW (RBC Distribution Width) particularly in the presence of normal blood profiles? The red cell distribution width (RDW) is a quantitative measure of the variability of RBC sizes in the sample (anisocytosis). The RDW is a function of MCV and, therefore, normal values vary slightly with age. However, normal values generally are between 12 and 14 percent .

What does it mean if I have low RDW? A low RDW (below 10.2%) means that the red blood cells vary very little in size. One reason for a low RDW level is macrocytic anemia. Another cause of a low RDW level is microcytic anemia. In these two disorders the red blood cells do not vary much in size because they are either all small or all large.

High red blood cell distribution width is closely associated with risk of carotid artery atherosclerosis in patients with hypertension Association between RDW and white blood cell count and hemoglobin. A high baseline RDW was found to be associated with hemoglobin level (P<0.05; Table 2) and white blood cell count. The latter was also significantly different among the RDW groups (P<0.01; Table 1).

- An RDW test is a red cell distribution width test, which is one of the parameters measured in blood tests, states Medscape. Higher RDW results mean that the patient's red blood cells have a greater variation in size or volume.
