In order to diagnose anemia another index, which is the hemoglobin amount per red blood cell (MCH), is also useful. While the normal result for MCH is 27 to 31 picograms/cell, the normal result for MCV is 80 to 100 femtoliters.

Depending on the results of the MCV level count found in the blood test, it can indicate different types of anemia like microcytic, normocytic or macrocytic anemia. For example, when results of MCV are below the normal range, this can be an indication of microcytic anemia, where blood cell sizes are small. The causes of microcytic anemia can include iron deficiencies and blood disorders.
