Red Cell Distribution Width Coefficient of Variation (RDW-CV) Analysis
Red Cell Distribution Width (RDW) is a measurement that shows the variation in size or volume of red blood cells. It's expressed as a percentage and provides information on the range of sizes of the red blood cells circulating in the bloodstream. This provides valuable information about the uniformity or heterogeneity of red blood cell sizes in a blood sample.
RDW Reference Range:
Normal Range: 11.5% to 14.5%.
Normal RDW suggests a uniform size among the red blood cells, which is typically seen in healthy individuals.

High RDW levels can serve as early markers for nutritional deficiencies or bone marrow issues, often alerting doctors to potential problems before other blood test results change. Treatments may range from dietary supplements, like iron, vitamin B12, or folate, to more specific therapies for underlying conditions. By integrating RDW assessments with a comprehensive evaluation of health and medical history, healthcare providers can tailor treatment approaches effectively, ensuring the best possible management of blood health issues.
