Is There Any Significance to Slightly Elevated MCV and MCH?

The significance of a slight elevation of MCV and MCH levels is an anemic condition of the red blood cells. Anemia is characterized by a low red blood cell count or a deficiency in the hemoglobin in the blood, translating to an oxygen deficient condition for the body tissue.

A complete blood count, CBC, evaluates the condition of the all of the individual components in the blood, red and white blood cells, platelets and plasma. An abnormal reading for the red blood cell count, RBC, either too high or too low in value, indicates anemia and leads to oxygen deprivation of the body tissues. A high RBC reading, polycythemia, indicates a need for further testing to pinpoint the exact diagnosis. After additional testing, a plan to explore the available treatment options is devised.

The normal range for the mean corpuscle volume, MCV, on a CBC is between 80 and 100 femtoliter per red cell in adults, but vary according to the age of the patient and the laboratory’s definition a normal range. A slightly elevated level of MCV on a CBC signifies macrocytic anemia, a diagnosis of abnormally large blood cells.

Readings of the mean corpuscle hemoglobin, MCH, within the range of 27 to 31 picograms per cell are considered normal. A slight elevation of the MCH level signifies a higher than usual amount of hemoglobin in the red blood cells. The color of these cells is darker than usual and the resulting condition is called hyperchromic anemia.
