It means there is variation in the size of red blood cells- some are smaller, some are bigger. It could be due to many things, and this alone does not indicate any particular condition.
If you have this data in front of you from a CBC and so does your doctor, you should ask him/her if there is any concern. Most blood test code your results with critical markers on the paper to get the attention of whomever your paperwork is being viewed by but you can never leave it to chance they will see it - or in most cases the doctor is already working your blood scores into his diagnosis silently.
There is no one single answer for blood results but if you haven't lost blood in any way recently (i.e. donated blood, menstruation, bad cut) and you have a high RDW, your body is making possibly too many immature cells too fast and that most definitely needs further investigated.
what does high RDW in hematology test refer to?
if rdw is high
nothing if the RDW and MCV are normal
anaemia
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.
RDW (Red blood cell Distribution Width) - Describes how much your red blood cells differ in size from one another. The lower the number, the more uniform in size. A RDW under 15.0% is considered "normal". A RDW of 15.2% is not significantly high and shouldn't be cause for concern.
iron deficiency
means a sign of inflamation level in body
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-CV stands for Red Cell Distribution Width - Cell Volume. It means that the red blood cells vary a lot in size.
Low Mean Corpuscular Hemoglobin High Red cell distribution width.
it is in megaloblastic anaemia
