Why is RDW high in iron deficiency anemia?
As iron deficiency progresses, decreased erythropoeisis develops. New erythrocytes are smaller, causing the RDW to increase slightly, as there is a mix of older normocytic cells with younger microcytic cells. Laboratory findings include low ferritin, low MCV, high RDW, and increased transferrin.
What if Rdw in blood test is low?
Low RDW. A low value indicates that your red blood cells are uniform in size. This is desirable and not a cause for concern [3]. However, it is still possible to have a blood-related disease and low RDW levels [3].
What does Rdw mean in a blood test?
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.
How do you fix high RDW?
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.
What is MCV MCH MCHC RDW in blood work?
Mean corpuscular volume (MCV): Average size of red blood cells. Mean corpuscular hemoglobin (MCH): Amount of hemoglobin per red blood cell. Mean corpuscular hemoglobin concentration (MCHC): Hemoglobin amount relative to cell size. Red cell distribution width (RDW): Variability in red blood cell size.
What does low MCV and MCh mean?
Nutritional deficiencies can cause anemia; if you are anemic, your laboratory tests show a low MCH, or mean corpuscular hemoglobin, and low MCHC, or suggest corpuscular hemoglobin concentration. MCH and MCHC are used to identify anemia and can help determine what type of anemia you have.
What causes elevated RDW?
Another cause of a high RDW level and a low MCV level is thalassemia intermedia. Thalassemia intermedia is another type of blood disorder in which there is impaired production of one or more of the elements that make up hemoglobin. These numbers can be associated with a wide variety of conditions.
What if my MCV is low?
Low intake of Vitamin B6
What causes High RDW?
RDW can be high due to: B12 and Pernicious anemia; folic acid anemia; iron deficiency anemia; hemolytic anemia; transfusions; sideroblastic anemia; or alcohol abuse. A low RDW can indicate any of the following: iron deficiency anemia due to parasites, blood loss, or poor iron absorption; vitamin B6 anemia; or rheumatoid arthritis (RA).
