RDW-CV stands for Red Cell Distribution Width - Cell Volume. It means that the red blood cells vary a lot in size.
iron deficiency
means a sign of inflamation level in body
A low RDW-cv on a hematology test means that there is a very small variation in the size of your red blood cell. Low RDW means that the cells are mostly the same size, while high RDW means the sizes are different.

what does high RDW in hematology test refer to?
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 .
it is in megaloblastic anaemia
