What is high RDW in blood test low?
What is high RDW in blood test low?
Instead, it refers to the difference in size from your largest to your smallest red blood cell. A low RDW means your red blood cells are all about the same size. A high RDW means you have both very small and very large red blood cells. You may also have a “normal” RDW.
What does the RDW blood test look at?
Unlike some other blood tests, the RDW does not measure your red blood cell count. Instead, it measures red blood cell variation and looks at their shape and size. The job of red blood cells is to carry oxygen from your lungs to the rest of your body.
What does red cell distribution width ( RDW ) mean?
A red cell distribution width (RDW) test is one of the parameters tested when you get a CBC test performed. Read on to learn about high and normal results and what each value means. What Does an RDW Measure?
What causes low RDW on CBC blood test?
Polycythemia is a red blood cells disorder and not affect the RBC’s shape, as it causes over production of red cells alone. Hemoglobin is the primary key for anemia, read about the normal hemoglobin. Low RDW is due to false estimation, abnormal counting background can cause false low RDW estimation.
What does a normal RDW and MCV reading mean?
A normal RDW and MCV reading could indicate that you are suffering from chronic anemia, acute blood loss, or renal disease. Hence, RDW should always be checked along with other blood components. That is the reason why it is included in the routine complete blood count test. (9, 10)
What does RDW on a blood test mean?
A red cell distribution width (RDW) test is a measurement of the range in the volume and size of your red blood cells (erythrocytes). Red blood cells move oxygen from your lungs to every cell in your body. Your cells need oxygen to grow, reproduce, and stay healthy.
What should my RDW results be for my child?
The normal red blood cell distribution width in children will be slightly different. The RDW test results for children should be between 12% and 14% depending on their age.
What are the effects of High RDW levels?
Studies show that higher RDW is associated with inflammation and higher levels of inflammatory cytokines, such as IL-6, IL-8, and TNF-alpha [ 6, 17, 18, 19, 20, 1, 21 ]. Inflammatory cytokines can hinder red blood cell production, and thereby increase RDW levels.

What does it mean when your RDW is too high?
High results If your RDW is too high, it could be an indication of a nutrient deficiency, such as a deficiency of iron, folate, or vitamin B-12. These results could also indicate macrocytic anemia, when your body doesn’t produce enough normal red blood cells, and the cells it does produce are larger than normal.
What should I do to lower my RDW level?
1) Eat a Balanced Diet Eat a healthy and nutritious diet in order to prevent nutrient deficiencies. It is important that your diet includes enough iron, folate, and vitamin B12 [ 8, 11, 12 ]. Correcting nutritional deficiencies can help improve red blood cell production and decrease RDW levels.
