What is RDW in a blood test
A. RDW stands for the red blood cell distribution width. This is a standard reported measure on a complete blood count (CBC) lab test.It measures the variability in red blood cell size. In the normal state, red blood cells are continually being produced and removed from the blood at a steady rate.7 Followers. A. RDW stands for the red blood cell distribution width.

RDW stands for the red blood cell distribution width. This is a standard reported measure on a complete blood count (CBC) lab test. It measures the variability in red blood cell size. Red cell distribution width (RDW) laboratory test is a part of a standard complete blood count (CBC), and it is used along with other RBC indices, especially mean corpuscular volume (MCV) to help determine the causes of anemia.DW is elevated in accordance with variation in red cell size (anisocytosis), ie, when elevated RDW is reported on complete blood count, marked anisocytosis (increased variation in red cell size) is expected on peripheral blood smear review. Human red blood cells. Red blood cell distribution width (RDW-CV or RCDW and RDW-SD) is a measure of the range of variation of red blood cell (RBC) volume that is reported as part of a standard complete blood count. Usually red blood cells are a standard size of about 6-8 μm in diameter.uman red blood cells.

Usually red blood cells are a standard size of about 6-8 μm in diameter. 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.t is virtually impossible to discuss the RDW aspect of a blood test without including MCV, or mean corpuscle value. MCV goes hand in hand with red blood cell distribution width (RDW) in terms of anemia and other hematology disorders, and the values of both are influenced by each other. The RDW blood test can calculate the sizes of red blood cell count in a sample of blood, and normally an RDW test is performed as a part of a CBC test, which means complete blood count. The RDW blood test is dependent on the draw of another test, which is MCV, the mean corpuscle value.MCV and RDW are closely related when it comes to anemia and many other hematology disorders. The values influence each other.f your primary care provider diagnoses you with iron deficiency or anemia, your RDW blood test showed a low count. These levels, along with other combinations of blood counts, allow your physician to determine what kind of anemia is affecting you, and why it has presented symptoms. 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).he red blood cell distribution width (“RDW”) test is normally done when the complete blood count is ordered by the health practitioner. If the RDW level is increased and the MCV level is normal. This can be caused by the beginning stages of a decrease in vitamin B12 or folic acid (a type of vitamin) in the body.It can also be caused by the beginning stages of iron deficiency anemia.f the RDW level is increased and the MCV level is normal. This can be caused by the beginning stages of a decrease in vitamin B12 or folic acid (a type of vitamin) in the body. Red Cell Distribution Width RDW = Red cell Distribution Width. A measure in variation of the sizes of the Erythocytes (red blood cells) RDW stands for red cell distribution wi … dth. It is a measure of the variability of the size (volume) of red cells.Red cells of uniform size--no matter what that size is--will have a low RDW.f the RDW level is increased and the MCV level is normal. This can be caused by the beginning stages of a decrease in vitamin B12 or folic acid (a type of vitamin) in the body.
