nothing if the RDW and MCV are normal
Solon Zboncak
what does it mean when your RDW is 11.3? I know normal is 11.5-14.5. But how much ashould I be concerned?
Do your own search. Hah take that. Now you are just reading and wasting your time and you couldn't do anything about it. :)
Coeff of Variation = Mean/SD
RDW is Red cell Distribution Width. It is the difference in size of your red blood cells. (If they were all exactly the same size, the number would be low. If some were tiny and some were huge, the number would be high). An acceptable range is 11.5 to 14.5%. This means your value is higher, and you have higher amounts of variation in the size of your red blood cells. This could be due to any number of things, and this data by itself doesn't say much about any condition.
z=x-mean / sd

My RDW-SD was 37.80 fl

if rdw is high
Means that the variation in the size of your red blood cell is very small. That it! Inother words, no problem!RDW refers to the variation in size if your red blood cells.A low RDW means that the cells are all roughly the same size.A high RDW means there isa high variation in the sizes of the cells and usually means a deficiency of iron and/or B12.
RDW (Red Cell Distribution Width) reflects the variation in size of red blood cells. High RDW could indicate different types of anemia or vitamin deficiencies. SD (Standard Deviation) is a measure of variability in a set of values, in this case, red blood cell distribution. Low MCH (Mean Corpuscular Hemoglobin) means there is less hemoglobin in each red blood cell, which could suggest anemia or iron deficiency.
low in B12 or iron
low folate levels
iron deficiency
Well to all the people who are interested: These are hematological parameters that indicate an underlying anemic condition. The normal RBC is spherical and biconcave with a diameter of 6-8 micrometer. any variation in size is termed as anisocytosis and in shape is termed as poilikocytosis. These variations are seen in anemic conditions like iron or folate or Vitamin B12 deficiency or others. Earlier when blood samples were analyzed manually under microscope the terms aniso and poikilocytosis were used, when such variations were observed, but with the advent of computerized automated blood analysis methods newer terms like RDW, RDW-SD, RDW-CV have come into place, these terms also indicate unusual variations in the size and shape of RBC which are highly indicative of a possible Anemic conditions. RDW stands for Red Cell Distribution Width RDW- SD stands for Standard Deviation in RDW RDW-CV stands for Coefficient Variation of RDW These are technical terms used in computer interpretation of the given blood samples If your reports show abnormal values do consult your physician .
