The MCV is higher than normal when red blood cells are larger than normal. This is called macrocytic anemia. Macrocytic anemia can be caused by: Vitamin B-12 deficiency.
Similarly one may ask, what is normal mean cell volume?
MCV is elevated or decreased in accordance with average red cell size; ie, low MCV indicates microcytic (small average RBC size), normal MCV indicates normocytic (normal average RBC size), and high MCV indicates macrocytic (large average RBC size). The reference range for MCV is 80-96 fL/red cell in adult.
What does the volume of the cell represent?
As a cell grows bigger, its internal volume enlarges and the cell membrane expands. Unfortunately, the volume increases more rapidly than does the surface area, and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.
When a cell increases in size what is it called?
In cells. The increase in size and changes in shape of a developing organism depend on the increase in the number and size of cells that make up the individual. Increase in cell number occurs by a precise cellular reproductive mechanism called mitosis.
