RBC Indices: When a blood count (CBC) is done the lab describes the red cells (rbcs). The RDW describes the variation in cell size as a percentage. Normal is ~12-15%. A normal rdw-sd is ~35-46. High rdws usually result from increased rbc production, rbc damage, or transfusions. We look at MCHC more than mch. The MCHC gives the percent of a rbc made up of hemoglobin. The MCV is the avg volume of rbcs.

meaningless: Rdw has no meaning unless you are anemic and your MCV is low. Mch also has no meaning.
