mean corpuscular volume
Quick Summary
Mean corpuscular volume (MCV) is a measurement used in blood analysis to determine the average size of red blood cells. In a healthy individual, the MCV typically ranges from 82 to 92 cubic micrometers.123
An elevated MCV indicates that red blood cells are larger than normal, a condition known as macrocytic anemia. This can result from deficiencies in vitamin B12 or folic acid, which are crucial for red blood cell production and maturation.12
Conversely, a low MCV signifies that red blood cells are smaller than normal, a characteristic of microcytic anemia. This is often caused by iron deficiency, as iron is essential for hemoglobin formation. When iron is insufficient, the body produces smaller red blood cells that are poorly filled with hemoglobin.12
Accurate MCV measurement is vital for diagnosing the specific type of anemia, as treatment varies significantly depending on the underlying cause.123
