Mean corpuscular volume (MCV) is a measure of the average size of red blood cells (RBCs) in a sample of blood. It is obtained from a complete blood count (CBC) test, which is a routine blood test used to measure the number and types of cells in the blood.

To obtain the MCV, a sample of the patient's whole blood is taken and placed in a special machine called a hematology analyzer. The analyzer measures the size of the RBCs and calculates the average size, which is the MCV. The MCV is then reported as part of the CBC results.
