RDW BLOOD TEST RDW BLOOD TEST. The red blood cell distribution width (“RDW”) 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 μm).

What does it mean if I have low RDW? A low RDW (below 10.2%) means that the red blood cells vary very little in size. One reason for a low RDW level is macrocytic anemia. Another cause of a low RDW level is microcytic anemia. In these two disorders the red blood cells do not vary much in size because they are either all small or all large.

Top 30 Doctor insights on: High Rdw And Low Mch Means Get help from a doctor now ›. Blood count terms: Rdw means red cell distribution width, which is the range of values for the width of your red blood cells. A higher number could mean that you are making lots more red cells for some reason. Mch mean mean (or average) red cell hemoglobin, which is the amount of hemoglobin in each red blood cell. If it's low, this means that your cells aren't carrying as much hemoglobin as they should. ...Read more.

What Is RDW In Blood Test And What Does A High RDW Count Mean? The blood with all its different markers is a good indicator of health. Knowing what indicator depicts can help deal with deficiencies. RDW count stands for Red blood cell distribution width. This count measures the size of the volume of the red blood cells and not the size of the blood cells itself.The blood cells are responsible for carrying oxygen from lungs to organs and carbon dioxide to the lungs for exhalation. high RDW count with a low MCV could mean a chronic disease but a low RDW and a low MCV could mean anemia. A high RDW with a normal MCV could mean a B12 deficiency. A high MCV with a normal RDW could also show beginnings of leukemia. Both counts being high signify a folate deficiency.
