Doctor insights on:
Low but...: If you are asking about RDW that is part of a CBC report in United States, a value lower than 80 is usually considered low (different labs may have different norms). A low RDW may be suggestive of iron deficiency, thalassemia (or other altered red cells), or other blood problems. However, a value of 10.9 is too low unless a different measurement. ...Read more
Why do you ask?: The reference range on RDW, as for most labs, is set so that a few percent of folks fall outside on either end. A low RDW is never a problem. There is no advantage to trying to change it. Frequent visits to the blood bank are good for you as a public service, and are likely to raise RDW. ...Read more
Lab test: If the RDW-SD is up but everything else is normal, it's a tipoff that iron deficiency may be developing. There are many other possibilities. And remember that for every lab value, a few percent of healthies fall outside on either end. Glad you're interested in your lab work. Best wishes. ...Read more
Non-specific: Variation in red cell size can be due to many reasons, e.g., iron deficiency, hemolytic anemia, folate (folic acid) and/or B12 deficiency. All lab results need to be interpreted in the clinical context and the doctor who ordered the test is usually in the best position to do that. ...Read more
You don't want to: Rdw means reed blood cell distribution width is a measure of the variation of red blood cell (rbc) volume. Usually rbcs are a standard size of about 6-8 μm. Certain disorders, however, cause a significant variation in cell size. Certain disorders, like iron or vit B12 deficiency- cause a significant variation in cell size- thus will increase rdw. It is used to differentiate the cause of anemia. ...Read more
It depends: Rdw means red cell distribution width. It measures the difference between the sizes of the patient's red blood cells. It increases a little as one gets much older. The importance of it depends on evaluating the rest of the blood, and what shapes the red cells take. ...Read more
Red cell size:
Variablity. Rdw is the short term for distribution of red cell width and reflects variation in red cell size. The variation may be due hemolytic anemia, microvascular disease, hemoglobin disorders, iron deficiency anemia etc. See this site for more info.

Thanks for asking!: Rdw stands for red blood cell distribution width, which is a measured parameter in a CBC test. High RDW value indicates greater variation in rbc size. This may be associated with iron deficiency anemia, folate/b12 deficiency anemia, mixed deficiency, recent hemorrhage, . ..Etc. ...Read more
Absolutely not: It's got nothing to do with polycythemia. It means that your red cells vary in size. This often means nothing whatsoever, especially if it's the only blip on your lab slip and your iron status is normal on your chemical profile. Rdw generally rises in iron deficinecy before anemia appears, so it may be a heads up. ...Read more
My rdw-cv is 19.6% and is high. What other tests are required and what are the possible health problems.
CBC.: Rdw-cv measures the variability of red cell size. It is useful in finding the cause of anemia, or detecting early deficiencies of iron, B12 or folic acid. Rdw can be effected by alcohol, medications, chronic health conditions, so is not helpful by itself. It has to be viewed in the context of the rest of the CBC (complete blood count) and your health history. ...Read more
My question is my Dr. Ran test and one week ago the RDW was 14.8. 11 months ago the test was 15.1. Please can you explain what all this means. I s?
Not to: Meaningful. It has todo with the variation In size of your red cells. Not to worry ...Read more
How's iron level?: The MCV is lowish, about where mine usually runs, but not inconsistent with good health. RDW tends to rise in early iron deficiency, before anemia appears, but this is by no means the only possibility. If you may be iron deficient (vegetarianism, heavy periods, pregnancy), your physician may check iron and iron binding capacity & discuss possible supplementation. Glad you asked, best wishes. ...Read more
Maybe: This isn't a danger to life, but a good follow-up might be a check to see if you're becoming a bit iron-deficient, even if you're not anemic yet. If you're iron-deficient, see if you and your physician can figure out why. Best wishes. ...Read more
RBC size variation: Rdw is a a statistical measurement of the differences in size of the red blood cells (rbc). Higher RDW values mean that there is more variation in the sizes of the rbc. Iron deficiency anemia is associated with increased rdw, especially after iron replacement starts. ...Read more
Need more info: Why were these tests done? What are the rest of results? What are the actual values of MCV, MCH, MPC and RDW. It would be helpful to discuss these results with your doctor who knows your health history. ...Read more
Blood count terms:
Rdw means red cell distribution width, which is the range of values for the width of your red blood cells. A higher number could mean that you are making lots more red cells for some reason.
Mch mean mean (or average) red cell hemoglobin, which is the amount of hemoglobin in each red blood cell. If it's low, this means that your cells aren't carrying as much hemoglobin as they should. ...Read more
Red cell distributio: It means the red cells in the blood are not all the same size. When someone has anemia, the RDW test can be used as extra info to find out what the anemia is from. Glucose means th sugar in the bloodstream. If it is high it could be a aign of diabetes in certain cases. It is unrelated to rdw. ...Read more
Random Dist Width: Random distribution width (RDW) is a measure of the variability of the sizes (volume) of the red blood cells in a complete blood count. The lower the number, the more similar are the sizes of the red cells. The higher the rdw, the more variable are the red cells in sizes (from small to large). The variability in red cell sizes can sometimes help narrow down the causes of anemia in a patient. ...Read more
Hematology: If the red cell, total white blood cell and platelet counts, as well as the MCV and MCH are all normal, the low MCHC and high RDW may not be significant or diagnostic. Low lymphocytes combined with high neutrophils can be seen in certain infections, use of corticosteroids, or in blood dyscrasias. However this question can be better answered by your MD (who knows your results) or a hematologist ...Read more
Size variation: It means nothing by itself; plus, hopefully you know that all lab reference ranges are set so that a few percent of healthies fall outside on either end. Early iron deficiency raises RDW before anemia begins but often it's up for no apparent reason. Mine's usually high because I donate blood. Don't worry about it. ...Read more
Don't Rx a lab: Early iron deficiency often does this, but remember that lab reference ranges are set so that a few percent of healthies fall outside on either end. Especially, don't get all worried about trying to adjust a lab value back into reference range; something is always outside. ...Read more
What does it mean when the MCV is normal and RDW is low and what does it mean when the grf is 87?
Nothing.: Mcv is red cell size. Rdw is the variation in red cell size. A low RDW has no meaning. Gfr is a way of measuring kidney function, and a GFR over 60 is of no concern. ...Read more
