mean corpuscular volume (MCV)
The mean corpuscular volume (MCV) is the typical volume of one erythrocyte (red blood cell). It is expressed in femtoliters (fl). Normal human values of MCV range from 80 to 100 fl. Abnormal values are referred to as micro- or macro-cythaemia. MCV can be calculated as Hct/RBC (i.e. the ratio of hematocrit to red blood cell count).
