What RDW CV means?

RDW CV, or Red Cell Distribution Width Coefficient of Variation, is a blood test parameter that measures the variation in size of red blood cells (RBCs). It is expressed as a percentage, indicating how much the sizes of the RBCs differ from the average size. A higher RDW CV value suggests greater variation in red blood cell size, which can be indicative of various medical conditions, including anemia or other blood disorders. It is often used alongside other blood tests to help diagnose and monitor these conditions.
