A low RDW (below 10.2%) means that the red blood cells vary very little in size. One reason for a low. RDW level is macrocytic anemia. Macrocytic anemia is a blood disorder in which not enough red blood. cells are produced, but the ones that are present are large. Another cause of a low RDW level is. microcytic anemia. Iron is an essential mineral needed to make red blood cells, and low amounts can lead to anemia, causing headaches, pale skin, fatigue, and other symptoms. Insufficient dietary intake of iron MCH, or mean corpuscular hemoglobin, is a measurement of the average amount of hemoglobin in a single red blood cell. Hemoglobin is a protein found in red blood cells that carries oxygen throughout the blood. MCH is part of a group of tests called red blood cell indices, which measure the size, shape, and quality of your red blood cells. An MCV blood test is often part of a complete blood count (CBC). A CBC is a common blood test that measures many parts of your blood, including red blood cells. It is used to check your general health. An MCV test may also be used with other tests to help diagnose or monitor certain blood disorders, including anemia. Anemia is described as a reduction in the proportion of the red blood cells. Anemia is not a diagnosis, but a presentation of an underlying condition. Whether or not a patient becomes symptomatic depends on the etiology of anemia, the acuity of onset, and the presence of other comorbidities, especially the presence of cardiovascular disease. Most patients experience some symptoms related to What are Low / Normal / High MCV Levels? The mean corpuscular volume is measured in femtolitre (fL). According to Dr. Jerry R. Balentine on MedicineNet, the average MCV levels for an adult is between 80 and 100 fL. 2 . Low MCV levels of below 80 fL are classed as microcytic anemia. High MCV levels of more than 100 fL in an adult are referred to Complete blood count (CBC): CBC is often the first investigation in a suspected case of thalassemia. A CBC showing low hemoglobin and low MCV is the first indication of thalassemia, after ruling out iron deficiency as the cause of anemia. The calculation of the Mentzer index (mean corpuscular volume divided by red cell count) is useful. A It is used along with other red blood cell (RBC) indices, especially mean corpuscular volume (MCV), to help determine the causes of anemia. RDW is elevated in accordance with variation in red cell size (anisocytosis); that is, when elevated RDW is reported on complete blood count, marked anisocytosis (increased variation in red cell size) is .
