RDW BLOOD TEST. The red blood cell distribution width (âRDWâ) test is normally done when the complete blood count is ordered by the health practitioner. The RDW test measures the variations in size of red blood cells. It is used with the MCV (mean corpuscular volume) test results to better determine types of anemia. Normally red blood cells are between six to eight micrometers in diameter (a micrometer is one millionth of a meter and its symbol is Î¼m).
RDW is the abbreviation for red blood cell distribution width.. According to Lab Tests Online, RDW calculates the varying sizes of red blood cell (RBC) volume in a blood sample. An RDW test is usually performed as part of a CBC, or complete blood count.DW is calculated by dividing the standard deviation (SD) by the mean corpuscle volume (MCV) and then multiplying that result by 100. The standard deviation represents the volume of erythrocytes or red blood cells that are in the blood smear.
