RBC distribution width
Red blood cell distribution width in blood samples
Red blood cell distribution width (RDW) is a measure of the range of variation of red blood cell volume. The variable is measured with a complete blood count performed by Quest Diagnostics. See the routine laboratory tests subcategory description for blood sample collection and analysis procedures.
RDW is expressed as a percentage.
