Mean corpuscular volume (MCV) is the average volume of a red blood cell and is calculated by dividing the hematocrit (Hct) by the concentration of red blood cell count. [citation needed] = [] Normal range: 80–100 fL (femtoliter)
The MCV can be conceptualized as the total volume of a group of cells divided by the number of cells. For a real world sized example, imagine you had 10 small jellybeans with a combined volume of 10 μL. The mean volume of a jellybean in this group would be 10 μL / 10 jellybeans = 1 μL / jellybean. A similar calculation works for MCV.
This parameter is, therefore, not influenced by the average RBC size (mean corpuscular volume, MCV). [7] RDW-CV (expressed in %) is calculated with the following formula: RDW-CV = (1 standard deviation of RBC volume ÷ MCV) × 100%. [8] Since RDW-CV is mathematically derived from MCV, it is therefore affected by the average RBC size (MCV). [7]
The normal mean corpuscular volume (abbreviated to MCV on full blood count results, and also known as mean cell volume) is approximately 80–100 fL. When the MCV is <80 fL, the red cells are described as microcytic and when >100 fL, macrocytic (the latter occurs in macrocytic anemia). The MCV is the average red blood cell size.
The Mentzer index, described in 1973 by William C. Mentzer, [1] is the MCV divided by the RBC count. It is said to be helpful in differentiating iron deficiency anemia from beta thalassemia trait. [2] [3] The index is calculated from the results of a complete blood count.
Normocytic anemia is a type of anemia and is a common issue that occurs for people typically over 85 years old. Its prevalence increases with age, reaching 44 percent in men older than 85 years. [1]
The low protein theory for the pathogenesis of kwashiorkor has been used to teach that capillary exchange between the lymphatic system and circulating blood is impaired by a reduced oncotic (i.e. colloid osmotic pressure, COP) in the blood, as a consequence of inadequate protein intake, so that the hydrostatic pressure gradient, which favors ...
Reticulocytes are a valuable tool for biologists who study protein translation. Reticulocytes are unusual among cells in that they contain all of the machinery necessary to translate proteins but lack a nucleus. Since a cell's nucleus contains many components that make studying translation difficult, these cells are quite useful.
