What do my blood tests mean? 1 Mean corpuscular hemoglobin concentration (MCHC) is a calculation of the average concentration of hemoglobin inside a single red blood cell.  Red cell distribution width (RDW) is a calculation of the variation in the size of RBCs.

"What Are ""RDW-CV"" and ""RDW-SD?""" RDW-CV and RDW-SD are a measurement of the size of red blood cells, according to Med-Health.net. RDW-SD is an actual measurement, while RDW-CV involves some calculations using the RDW-SD deviation.

Red blood cell distribution width 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.

Red Cell Distribution Width (RDW) RDW is elevated in accordance with variation in red cell size (anisocytosis), ie, when elevated RDW is reported on complete blood count, marked anisocytosis (increased variation in red cell size) is expected on peripheral blood smear review. The reference range for RDW is as follows: RDW-SD 39-46 fL.

- 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.

- RDW: RDW=red cell distribution width. This is a statistical measure or the degree of variation in sizes of the red cells. It is a useful parameter ini classifying anemias that may otherwise be similar, for example iron deficiency and some thalassemias. But other parameters are more generally useful.

It is INDEED THE COEFFICIENT OF VARIATION of the red blood cells in the sample (standard error/mean*100). Large values implies that there could be several clones of RBC circulating.

How can we interpret the value of RDW in complete blood count? In observing the RDW and the red cell plots showing this value, the level of response to the treatment of anaemia within that patient can be assessed. A good response to iron therapy can give a high RDW >20 and a clear double-peak can be observed. A poor response to treatment will have a small / negligable change in RDW from the norm.
