Rdw cv high means: RDW-CV means Red Cell Distribution Width

RDW-CV means Red Cell Distribution Width Coefficient of variation is a blood test that is performed to detect the size variation in your red blood cells. RDW-CV blood test calculation is derived from the standard deviation of red blood cell volume and the mean corpuscular volume. If an RDW-CV value is high, it indicates a higher range of variation in the sizes of red blood cells, suggesting a potential health concern. RDW-CV reflects the variation in normal red blood cell sizes. Typically ... Other Tests RDW results will be considered in the context of additional indices you'll find on your CBC report. In addition to the aforementioned MCV, MCH, and MCHC, these include: Red blood cell (RBC) count White blood cell (WBC) count Hemoglobin and hematocrit count Mean platelet volume (MPV) Variation in red blood cell size may also be noted visually by looking at a peripheral smear for morphology. This test is usually done after a CBC to investigate an abnormality. In a peripheral blood ... Red cell distribution width (RDW) blood test measures how red blood cells vary in volume and size. Major differences or a high RDW may indicate a medical condition. A red cell distribution width (RDW) blood test helps measure variation in red blood cell volume and size.
