Rdw cv high means: A high red cell

A high red cell distribution width (RDW) indicates heterogeneity in red blood cell size (anisocytosis) and serves as an important diagnostic marker for various conditions including iron deficiency anemia, inflammatory disorders, and cardiovascular diseases, requiring targeted investigation of the underlying cause rather than treatment of the ... Curious about your RDW CV blood test? Learn what dangerously high RDW CV levels mean, what causes them, and how to respond with our easy-to-read, conversational guide. 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 ...
