What is low Rdw in blood test?

A low RDW (below 10.2%) means that the red blood cells vary very little in size. One reason for a low RDW level is macrocytic anemia. Another cause of a low RDW level is microcytic anemia. In these two disorders the red blood cells do not vary much in size because they are either all small or all large.

Thereof, what does it mean when your RDW is low?

Instead, it refers to the difference in size from your largest to your smallest red blood cell. A low RDW means your red blood cells are all about the same size. A high RDW means you have both very small and very large red blood cells. You may also have a “normal” RDW.

Likewise, how do you fix low RDW? To treat this, your doctor may recommend the following:

  1. Increase iron in your diet with foods like spinach.
  2. Take iron supplements.
  3. Get more vitamin B-6, which is necessary for proper absorption of iron.
  4. Add more fiber to your diet, which can help improve the intestinal absorption of iron.

Also to know, does low Rdw mean cancer?

Recent case control studies have shown associations between RDW and colon cancer and malign biliary obstruction. In addition, RDW has been shown to predict cancer in patients with unintentional weight loss, and to be associated with poor prognosis in patients with lung cancer and multiple myeloma.

What is Rdw in blood test normal range?

Red blood cell distribution width (RDW or RDW-CV or RCDW and RDW-SD) is a measure of the range of variation of red blood cell (RBC) volume that is reported as part of a standard complete blood count. Normal reference range of RDW-CV in human red blood cells is 11.5-14.5%.
