MCV – (Mean Corpuscular volume) 平均红血球容积

A measurement of the average size of the red blood cells (RBC). The MCV is elevated when RBCs are larger than normal (macrocytic) for example in anemia caused by B12 and Folic acid deficiency. When MCV is decreased, the RBC is smaller than normal (microcytic) such as seen in iron deficiency anaemia. Very low level indicates chronic blood loss.
