Often, they’ll look at the results of an RDW (variation in red blood cell size) alongside the results of the MCV (average red blood cell size) to assess the health of your red blood cells. Low RDW A low RDW isn’t usually a cause for concern and isn’t associated with any particular types of anemia.
2 Μαρ 2021 · Low RDW. A low value indicates that your red blood cells are uniform in size. This is desirable and not a cause for concern .

20 Μαΐ 2024 · a high RDW and typical MCV suggest an iron, B12, or folate deficiency or possibly chronic liver disease; a high RDW and low MCV suggest iron deficiency or microcytic anemia
Medical Tests →. RDW (Red Cell Distribution Width) What is a red cell distribution width test? A red cell distribution width (RDW) test measures how much the volume and size of your red blood cells (erythrocytes) varies. Red blood cells are made in your bone marrow (the spongy tissue inside your large bones).
Testing. Anemia is a decrease in the number of red blood cells (RBCs) as measured by the red cell count, the hematocrit, or the red cell hemoglobin content. In adult males, anemia is defined as any of the following: Hemoglobin < 13.6 g/dL (< 1360 g/L) Hematocrit < 40% (< 0.40) RBC < 4.5 million/mcL (< 4.5 × 1012/L)
