What is an MCV blood test? MCV stands for mean corpuscular volume. There are three main types of corpuscles (blood cells) in your blood–red blood cells, white blood cells, and platelets. An MCV blood test measures the average size of your red blood cells, also known as erythrocytes. Red blood cells move oxygen from your lungs to every cell in
What does a MCV level of 125 mean?
If the MCV goes up to an extreme of 125, it may indicate vitamin B12, folate deficiencies, or cold agglutinin disease. A higher MCV value indicates that the red blood cells are larger than the average size.
What does it mean if my MCV is high?
Iron-deficiency anemia is the most common form of anemia. If your results show that your red blood cells are larger than normal, it may indicate: If your MCV levels are not in the normal range, it doesn’t necessarily mean that you have a medical problem needing treatment.
What does a low MCV level of 80 mean?
Low MCV level When a person has an MCV level below 80 fl, this suggests they have microcytic anemia. Microcytic anemia is a type of anemia in which red blood cells are smaller than usual. Iron deficiency causes microcytic anemia.
What are the limitations of the MCV test?
Post-Transfusion: The most obvious limitation of the MCV is that it offers little value if a person has had a blood transfusion. In this case, the MCV would reflect the average size of transfused red blood cells combined with a person’s own red blood cells.
What is the formula for calculating MCV?
In calculating MCV, the hematocrit is multiplied by ten and divided by the red blood cell count measured in millions of cells per cubic millimeter of blood. MCV = hematocrit (percent) x 10 / red blood cell count (millions/mm3 blood)
