The MCV is a measure of the average volume of a red blood cell. It is determined by multiplying a volume of blood by the proportion of blood that is cellular (the Hct) and dividing that by the number of red blood cells in that volume. MCV is reported in Femtolitres (fL) and the normal range is 80 - 100 fL. It is part of a standard FBC and is used primarily to classify anaemia into Microcytic (MCV reduced), Normocytic (MCV normal) or Macrocytic (MCV raised)
