MCV (Mean Corpuscular Volume)
MCV stands for mean corpuscular volume. An MCV blood test measures the average size of your red blood cells.
What it is for
An MCV blood test is often part of a complete blood count (CBC), a group of tests that measures the number and type of cells in your blood. It is used to check your general health. An MCV test may also be used with other tests to help diagnose or monitor certain blood disorders, including anemia. There are several types of anemia, and each type has a different effect on the size, shape, and/or quality of your red blood cells. An MCV test can help diagnose which type of anemia you have.
