Definition & Meaning of "mean corpuscular volume"in English

What is "mean corpuscular volume"?

Mean Corpuscular Volume (MCV) is a measurement used to describe the average size of red blood cells. It is used to help evaluate and diagnose different types of anemia and other blood disorders. A high MCV is a sign that red blood cells are larger than normal, which could be related to conditions like vitamin B12 or folate deficiency. While a low MCV suggests that the red blood cells are smaller than usual, which could be due to iron deficiency anemia or thalassemia.
