What Is Rdw Means
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
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
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
What does an elevated RDW level mean if all other levels are within normal range? RDW level is 15.1%
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
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
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
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
My son (13) has a slightly elevated RDW (14.8%) and a slightly low mchc reading (32.5%). What does this mean?
Mixed bag: High GFR ---the kidney function is better than normal. If from a 24 hour urine over collection. If not, and this is from blood work, diabetes with kidney disease causing the globulin (kidney filters) to overwork or pregnancy. Rdw--nothing to worry unless anemic or too many rbcs. High creatinine-- kidney disease, excessive protein intake, bactrim/tagamet use, dehydration. ...Read more
All cells same size.: The red blood cell distribution width (RDW) is a measure of variation of red cell volume that is reported as part of a blood count. Usually red blood cells are a standard size (6-8 ?m). Certain disorders, however, cause a significant variation in cell size. Low RDW means less variation in size and can be seen when all cells are large (macrocytic anemia) or all cells are small (microcytic anemia). ...Read more
Means nothing: A high RDW is a measure of the variability in size among red cells. When it is low, it's a fluke of statistics, and you should ignore it -- lab "normals" are set so that a few healthy folks lie outside. I run a high RDW as a frequent blood donor, and elevation is a common first-hint that something may be unusual; many healthies have high rdw's for various reasons. Labs mean nothing in isolation. ...Read moreSee 2 more doctor answers
