What does a low RDW mean on a blood test?

Low RDW is good: Rdw refers to the variation in the size of red blood cells. Normal value is from 11.5 to 14.5. There is preliminary evidence that high RDW values may portend higher mortality, however, this information has not become part of the accepted medical facts. The data for this association is based on information gathered by the insurance industry.
