What if your RDW-CV is high?

A high RDW-CV (Red Cell Distribution Width-Coefficient of Variation) indicates greater variability in the size of red blood cells, which can be a sign of various conditions. It is often associated with anemia, nutritional deficiencies (such as iron, vitamin B12, or folate), and certain chronic diseases. A healthcare provider may recommend further tests to identify the underlying cause and determine appropriate treatment. Monitoring RDW levels can be important for managing overall health, especially in individuals with known risks for hematologic disorders.
