A low percentage of RDW (Red cell blood Distribution Width) has no clinical meaning and it is not a matter for concern.
It is called isocytosis and it means that RBCs (red blood cells) are very similar in size. It may be even consider a positive sign because the size of the RBCs is very similar and means no interference in their production.
The RDW (Red cell blood Distribution Width) is only useful when it is high to discern between different types of anemia.
Isocytosis has no clinical meaning and it is not something to be worried about.
It does not mean the existence of any disease and does not require any kind of treatment.
There are no medication or factors for a low RDW in a blood test.
It may be due an intrinsic characteristic of a person.
There is no disease with a RDW percentage below normal range.
A RDW percentage below the normal range is not a negative sign and therefore no action is required to increase the percentage.
