MCV - Definition

January 2017


Definition


MCV is the acronym for mean corpuscular volume, signifying the value measuring the mean volume of red blood cells in a blood sample. In cases of anemia, this value can guide investigation into the underlying causes, with microcytic anemia where MCV is inferior to 80 femtoliters (unit of measurement used in this context), macrocytic anemia when it is superior to 100fl, and normocytic anemia when it sits between these two values. The primary causes for increased MCV are chronic alcoholism and deficiency in certain vitamins, notably B12 and B9 (folates), with decreased MCV primarily caused by iron deficiency.
