A mean corpuscular volume, or MCV, level of 102 is not considered extremely high. Normal values range from about 80 to 100 femtoliters, and value ranges can vary slightly, depending on the laboratory, states MedlinePlus. When a MCV level exceeds the normal upper limit, it indicates macrocytic anemia.
A patient deficient in vitamin B12 or folate, or undergoing chemotherapy, can develop macrocytic anemia, notes MedlinePlus. Doctors classify anemia based on blood cell size. The mean corpuscular volume indicates the size of red blood cells, and the MCV test helps a doctor diagnose a patient's specific anemia and its cause. Patients need to discuss the results of their mean corpuscular volume tests with their doctors.
