mean corpuscular volume (MCV)

The typical volume of one erythrocyte (red blood cell). Mean corpuscular volume (MCV) is expressed in femto-liters (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).
