What does a low RDW CV mean?

A low RDW (Red Cell Distribution Width) CV (Coefficient of Variation) indicates that the red blood cells in the sample are of relatively uniform size. This can suggest a healthy state with fewer variations in cell size, often associated with conditions like thalassemia or certain types of anemia where red blood cell production is stable. However, it's essential to interpret RDW in conjunction with other blood parameters and clinical findings for an accurate diagnosis.
