Mean single volume of erythrocytes
The mean individual erythrocyte volume (mean corpuscular / cell volume, MCV) indicates the mean cell size of the peripheral erythrocytes and is one of four values used to classify anemia .
The normal range is between 80 and 98 fl (= µm 3 = 10 −9 µl).
<80 | microcytic anemia ( iron deficiency , ACD , thalassemia , erythropoietic protoporphyria ) |
80-98 | possibly normocytic anemia (ACD, kidney and liver diseases, hemolytic anemia , aplastic anemia ) |
> 98 | macrocytic anemia ( pernicious anemia , megaloblastic anemia , alcoholism , chemotherapy of malignant tumors) |
Megaloblastic anemia is when there is a vitamin B 12 or folic acid deficiency . In hemolytic anemia, large and small cells can be present at the same time. Macrocytosis without anemia can also occur with alcoholism.
