MCV is measured by multiplying the total volume of blood (both blood cells and plasma) by the proportion of blood that is purely cellular (referred to as hematocrit or HCT). That value is then multiplied by 10 and divided by the total number of erythrocytes (called the red blood cell (RBC) count). 2. MCV blood test results report the average size of your red blood cells in femtoliters (fL). The doctor will want to know whether that size is within the normal, low, or high range. A normal... MCV is an abbreviation for Mean Corpuscular Volume. MCV blood test is an integral part of routine hematological tests known as Complete Blood Count, Complete Blood Cell Count (CBC), or Full Blood Count (FBC). MCV measures the average size and volume of red blood cells floating in the blood . The MCV blood test measures the Mean Corpuscular Volume ( MCV ), which shows the average size of red blood cells. It is an important part of the complete blood count and helps detect problems such as anemia, bleeding, hypothyroidism, or chronic infections. Normal MCV values are usually between 80 and 100 fL, although the exact range may vary slightly by laboratory. Results outside this range can indicate conditions like iron deficiency anemia, megaloblastic anemia, or thalassemia.
